2024-07-14Avoid unhelpful internal error for incorrect recursive-WITH queries.Tom Lane
checkWellFormedRecursion would issue "missing recursive reference" if a WITH RECURSIVE query contained a single self-reference but that self-reference was inside a top-level WITH, ORDER BY, LIMIT, etc, rather than inside the second arm of the UNION as expected. We already intended to throw more-on-point errors for such cases, but those error checks must be done before examining the UNION arm in order to have the desired results. So this patch need only move some code (and improve the comments). Per bug #18536 from Alexander Lakhin. Back-patch to all supported branches.

2024-07-13Fix new assertion for MERGE view_name ... DO NOTHING.Noah Misch
Such queries don't expand automatically updatable views, and ModifyTable uses the wholerow attribute unconditionally. The user-visible behavior is fine, so change to more-specific assertions. Commit d5f788b41dc2cbdde6e7694c70dda54d829a5ed5 added the wrong assertion. Back-patch to v17, where commit 5f2e179bd31e5f5803005101eb12a8d7bf8db8f3 introduced MERGE view_name.

2024-07-13Don't lose partitioned table reltuples=0 after relhassubclass=f.Noah Misch
ANALYZE sets relhassubclass=f when a partitioned table no longer has partitions. An ANALYZE doing that proceeded to apply the inplace update of pg_class.reltuples to the old pg_class tuple instead of the new tuple, losing that reltuples=0 change if the ANALYZE committed. Non-partitioning inheritance trees were unaffected. Back-patch to v14, where commit 375aed36ad83f0e021e9bdd3a0034c0c992c66dc introduced maintenance of partitioned table pg_class.reltuples.

2024-07-13Make sure to run pg_isready on correct portAndrew Dunstan
The current code can have pg_isready unexpectedly succeed if there is a server running on the default port. To avoid this we delay running the test until after a node has been created but before it starts, and then use that node's port, so we are fairly sure there is nothing running on the port.

2024-07-13Fix lost Windows socket EOF events.Thomas Munro
Winsock only signals an FD_CLOSE event once if the other end of the socket shuts down gracefully. Because each WaitLatchOrSocket() call constructs and destroys a new event handle every time, with unlucky timing we can lose it and hang. We get away with this only if the other end disconnects non-gracefully, because FD_CLOSE is repeatedly signaled in that case. To fix this design flaw in our Windows socket support fundamentally, we'd probably need to rearchitect it so that a single event handle exists for the lifetime of a socket, or switch to completely different multiplexing or async I/O APIs. That's going to be a bigger job and probably wouldn't be back-patchable. This brute force kludge closes the race by explicitly polling with MSG_PEEK before sleeping. Back-patch to all supported releases. This should hopefully clear up some random build farm and CI hang failures reported over the years. It might also allow us to try using graceful shutdown in more places again (reverted in commit 29992a6) to fix instability in the transmission of FATAL error messages, but that isn't done by this commit.

2024-07-12Fix ALTER TABLE DETACH for inconsistent indexesAlvaro Herrera
When a partitioned table has an index that doesn't support a constraint, but a partition has an equivalent index that does, then a DETACH operation would misbehave: a crash in assertion-enabled systems (because we fail to find the constraint in the parent that we expect to), or a broken coninhcount value (-1) in production systems (because we blindly believe that we've successfully detached the parent). While we should reject an ATTACH of a partition with such an index, we have failed to do so in existing releases, so adding an error in stable releases might break the (unlikely) existing applications that rely on this behavior. At this point I don't even want to reject them in master, because it'd break pg_upgrade if such databases exist, and there would be no easy way to fix existing databases without expensive index rebuilds. (Later on we could add ALTER TABLE ... ADD CONSTRAINT USING INDEX to partitioned tables, which would allow the user to fix such patterns. At that point we could add more restrictions to prevent the problem from its root.) Also, add a test case that leaves one table in this condition, so that we can verify that pg_upgrade continues to work if we later decide to change the policy on the master branch.

2024-07-12Fix unstable test in 040_pg_createsubscriber.Amit Kapila
The slot synchronization failed because the local slot's (created during slot synchronization) catalog_xmin on standby is ahead of remote slot. This happens because the INSERT before slot synchronization results in the generation of a new xid that could be replicated to the standby. Now before the xmin of the physical slot on the primary catches up via hot_standby_feedback, the test has created a logical slot that got some prior value of catalog_xmin. To fix this we could try to ensure that the physical slot's catalog_xmin is caught up to latest value before creating a logical slot but we took a simpler path to move the INSERT after synchronizing the logical slot.

2024-07-11Fix possibility of logical decoding partial transaction changes.Masahiko Sawada
When creating and initializing a logical slot, the restart_lsn is set to the latest WAL insertion point (or the latest replay point on standbys). Subsequently, WAL records are decoded from that point to find the start point for extracting changes in the DecodingContextFindStartpoint() function. Since the initial restart_lsn could be in the middle of a transaction, the start point must be a consistent point where we won't see the data for partial transactions. Previously, when not building a full snapshot, serialized snapshots were restored, and the SnapBuild jumps to the consistent state even while finding the start point. Consequently, the slot's restart_lsn and confirmed_flush could be set to the middle of a transaction. This could lead to various unexpected consequences. Specifically, there were reports of logical decoding decoding partial transactions, and assertion failures occurred because only subtransactions were decoded without decoding their top-level transaction until decoding the commit record. To resolve this issue, the changes prevent restoring the serialized snapshot and jumping to the consistent state while finding the start point. On v17 and HEAD, a flag indicating whether snapshot restores should be skipped has been added to the SnapBuild struct, and SNAPBUILD_VERSION has been bumpded. On backbranches, the flag is stored in the LogicalDecodingContext instead, preserving on-disk compatibility. Backpatch to all supported versions.

2024-07-10Make our back branches compatible with libxml2 2.13.x.Tom Lane
This back-patches HEAD commits 066e8ac6e, 6082b3d5d, e7192486d, and 896cd266f into supported branches. Changes: * Use xmlAddChildList not xmlAddChild in XMLSERIALIZE (affects v16 and up only). This was a flat-out coding mistake that we got away with due to lax checking in previous versions of xmlAddChild. * Use xmlParseInNodeContext not xmlParseBalancedChunkMemory. This is to dodge a bug in xmlParseBalancedChunkMemory in libxm2 releases 2.13.0-2.13.2. While that bug is now fixed upstream and will probably never be seen in any production-oriented distro, it is currently a problem on some more-bleeding-edge-friendly platforms. * Suppress "chunk is not well balanced" errors from libxml2, unless it is the only error. This eliminates an error-reporting discrepancy between 2.13 and older releases. This error is almost always redundant with previous errors, if not flat-out inappropriate, which is why 2.13 changed the behavior and why nobody's likely to miss it.

2024-07-08Fix scale clamping in numeric round() and trunc().Dean Rasheed
The numeric round() and trunc() functions clamp the scale argument to the range between +/- NUMERIC_MAX_RESULT_SCALE (2000), which is much smaller than the actual allowed range of type numeric. As a result, they return incorrect results when asked to round/truncate more than 2000 digits before or after the decimal point. Fix by using the correct upper and lower scale limits based on the actual allowed (and documented) range of type numeric. While at it, use the new NUMERIC_WEIGHT_MAX constant instead of SHRT_MAX in all other overflow checks, and fix a comment thinko in power_var() introduced by e54a758d24 -- the minimum value of ln_dweight is -NUMERIC_DSCALE_MAX (-16383), not -SHRT_MAX, though this doesn't affect the point being made in the comment, that the resulting local_rscale value may exceed NUMERIC_MAX_DISPLAY_SCALE (1000).

2024-07-08Fix right-anti-joins when the inner relation is proven uniqueRichard Guo
For an inner_unique join, we always assume that the executor will stop scanning for matches after the first match. Therefore, for a mergejoin that is inner_unique and whose mergeclauses are sufficient to identify a match, we set the skip_mark_restore flag to true, indicating that the executor need not do mark/restore calls. However, merge-right-anti-join did not get this memo and continues scanning the inner side for matches after the first match. If there are duplicates in the outer scan, we may incorrectly skip matching some inner tuples, which can lead to wrong results. Here we fix this issue by ensuring that merge-right-anti-join also advances to next outer tuple after the first match in inner_unique cases. This also saves cycles by avoiding unnecessary scanning of inner tuples after the first match. Although hash-right-anti-join does not suffer from this wrong results issue, we apply the same change to it as well, to help save cycles for the same reason. Per bug #18522 from Antti Lampinen, and bug #18526 from Feliphe Pozzer. Back-patch to v16 where right-anti-join was introduced.

2024-07-06Fix incorrect sentinel byte logic in GenerationRealloc()David Rowley
This only affects MEMORY_CONTEXT_CHECKING builds. This fixes an off-by-one issue in GenerationRealloc() where the fast-path code which tries to reuse the existing allocation if the existing chunk is >= the new requested size. The code there thought it was always ok to use the existing chunk, but when oldsize == size there isn't enough space to store the sentinel byte. If both sizes matched exactly set_sentinel() would overwrite the first byte beyond the chunk and then subsequent GenerationRealloc() calls could then fail the Assert(chunk->requested_size < oldsize) check which is trying to ensure the chunk is large enough to store the sentinel. The same issue does not exist in aset.c as the sentinel checking code only adds a sentinel byte if there's enough space in the chunk.

2024-07-06Cope with <regex.h> name clashes.Thomas Munro
macOS 15's SDK pulls in headers related to <regex.h> when we include <xlocale.h>. This causes our own regex_t implementation to clash with the OS's regex_t implementation. Luckily our function names already had pg_ prefixes, but the macros and typenames did not. Include <regex.h> explicitly on all POSIX systems, and fix everything that breaks. Then we can prove that we are capable of fully hiding and replacing the system regex API with our own. 1. Deal with standard-clobbering macros by undefining them all first. POSIX says they are "symbolic constants". If they are macros, this allows us to redefine them. If they are enums or variables, our macros will hide them. 2. Deal with standard-clobbering types by giving our types pg_ prefixes, and then using macros to redirect xxx_t -> pg_xxx_t. After including our "regex/regex.h", the system <regex.h> is hidden, because we've replaced all the standard names. The PostgreSQL source tree and extensions can continue to use standard prefix-less type and macro names, but reach our implementation, if they included our "regex/regex.h" header.

The failed test was syncing failover replication slot to standby to test that we remove such slots after the standby is converted to subscriber by pg_createsubscriber. In one of the buildfarm members, the sync of the slot failed because the LSN on the standby was before the syncslot's LSN. We need to wait for standby to catch up before trying to sync the slot with pg_sync_replication_slots(). The other buildfarm failed because autovacuum generated a xid which is replicated to the standby at some random point making slots at primary lag behind standby during slot sync. Both these failures wouldn't have occurred if we had used built-in slotsync worker as it would have waited for the standby to sync with primary but for this test, it is sufficient to use pg_sync_replication_slots().

2024-07-01Preserve CurrentMemoryContext across notify and sinval interrupts.Tom Lane
ProcessIncomingNotify is called from the main processing loop that normally runs in MessageContext. That outer-loop code assumes that whatever it allocates will be cleaned up when we're done processing the current client message --- but if we service a notify interrupt, then whatever gets allocated before the next switch into MessageContext will be permanently leaked in TopMemoryContext, because CommitTransactionCommand sets CurrentMemoryContext to TopMemoryContext. There are observable leaks associated with (at least) encoding conversion of incoming queries and parameters attached to Bind messages. sinval catchup interrupts have a similar problem. There might be others, but I've not identified any other clear cases. To fix, take care to save and restore CurrentMemoryContext across the Start/CommitTransactionCommand calls in these functions.

Defaults to "--copy" but may be set to "--clone" or "--copy-file-range" to use the alternative stategies.

2024-06-30Add pg_combinebackup --copy optionTomas Vondra
Introduces --copy as an alternative to --clone and --copy-file-range. This option simply picks the default mode to copy files, as if none of the options was specified. This makes pg_combinebackup options more consistent with pg_upgrade, and it makes testing simpler.

2024-06-30Add headers needed by pg_combinebackup --cloneTomas Vondra
The code for file cloning existed, but was not reachable as it relied on constants from missing headers. Due to that, on Linux --clone always failed with error: file cloning not supported on this platform Fixed by including the missing headers to relevant places. Adding the headers revealed a couple compile errors in copy_file_clone(), so fix those too.

2024-06-30Make pg_createsubscriber warn if publisher has two-phase commit enabled.Tom Lane
pg_createsubscriber currently always sets up logical replication with two-phase commit disabled. Improving that is not going to happen for v17. In the meantime, document the deficiency, and adjust pg_createsubscriber so that it will emit a warning if the source installation has max_prepared_transactions > 0.

2024-06-30Make pg_createsubscriber more wary about quoting connection parameters.Tom Lane
The original coding here could fail with database names, user names, etc that contain spaces or other special characters. As partial test coverage, extend the 040_pg_createsubscriber.pl test script so that it uses a generated database name containing funny characters.

2024-06-28SQL/JSON: Always coerce JsonExpr result at runtimeAmit Langote
Instead of looking up casts at parse time for converting the result of JsonPath* query functions to the specified or the default RETURNING type, always perform the conversion at runtime using either the target type's input function or the function json_populate_type(). There are two motivations for this change: 1. json_populate_type() coerces to types with typmod such that any string values that exceed length limit cause an error instead of silent truncation, which is necessary to be standard-conforming. 2. It was possible to end up with a cast expression that doesn't support soft handling of errors causing bugs in the of handling ON ERROR clause. JsonExpr.coercion_expr which would store the cast expression is no longer necessary, so remove. Bump catversion because stored rules change because of the above removal.
