2019-10-25Remove obsolete information schema tablesPeter Eisentraut
Remove SQL_LANGUAGES, which was eliminated in SQL:2008, and SQL_PACKAGES and SQL_SIZING_PROFILES, which were eliminated in SQL:2011. Since they were dropped by the SQL standard, the information in them was no longer updated and therefore no longer useful. This also removes the feature-package association information in sql_feature_packages.txt, but for the time begin we are keeping the information which features are in the Core package (that is, mandatory SQL features). Maybe at some point someone wants to invent a way to store that that does not involve using the "package" mechanism anymore.

2019-10-25Avoid failure when selecting a namespace node in XMLTABLE.Tom Lane
It appears that libxml2 doesn't bother to set the "children" field of an XML_NAMESPACE_DECL node to null; that field just contains garbage. In v10 and v11, this can result in a crash in XMLTABLE(). The rewrite done in commit 251cf2e27 fixed this, somewhat accidentally, in v12. We're not going to back-patch 251cf2e27, however. The case apparently doesn't have wide use, so rather than risk introducing other problems, just add a safety check to throw an error. Even though no bug manifests in v12/HEAD, add the relevant test case there too, to prevent future regressions. Chapman Flack (per private report)
2019-10-25Revert "Revert part of commit dddf4cdc3."Tom Lane
This reverts commit c114229ca2519620703a4be4e38181290cad8c0a. Commit 1408d5d869925c8ea7ca01c2644e8903fbab23de should make it safe to include these headers in the natural order.
2019-10-25Get rid of useless/dangerous redefinition of bool in ECPG.Tom Lane
pgtypeslib_extern.h contained fallback definitions of "bool", "FALSE", and "TRUE". The latter two are just plain unused, and have been for awhile. The former came into play only if there wasn't a macro definition of "bool", which is true only if we aren't using <stdbool.h>. However, it then defined bool as "char"; since commit d26a810eb that conflicts with c.h's desire to use "unsigned char". We'd missed seeing any bad effects of that due to accidental header inclusion order choices, but dddf4cdc3 exposed that it was problematic. To fix, let's just get rid of these definitions. They should not be needed because everyplace in Postgres should be relying on c.h to provide a definition for type bool. (Note that despite its name, pgtypeslib_extern.h isn't exposed to any outside code; we don't install it.) This doesn't fully resolve the issue, because ecpglib.h is doing similar things, but that seems to require more thought to fix. Back-patch to v12 where d26a810eb came in, to forestall any unpleasant surprises from future back-patched bug fixes.

2019-10-25Improve management of statement timeouts.Tom Lane
Commit f8e5f156b added private state in postgres.c to track whether a statement timeout is running. This seems like bad design to me; timeout.c's private state should be the single source of truth about that. We already fixed one bug associated with failure to keep those states in sync (cf. be42015fc), and I've got little faith that we won't find more in future. So get rid of postgres.c's local variable by exposing a way to ask timeout.c whether a timeout is running. (Obviously, such an inquiry is subject to race conditions, but it seems fine for the purpose at hand.) To make get_timeout_active() as cheap as possible, add a flag in the per-timeout struct showing whether that timeout is active. This allows some small savings elsewhere in timeout.c, mainly elimination of unnecessary searches of the active_timeouts array. While at it, fix enable_statement_timeout to not call disable_timeout when statement_timeout is 0 and the timeout is not running. This avoids a useless deschedule-and-reschedule-timeouts cycle, which represents a significant savings (at least one kernel call) when there is any other active timeout. Right now, there usually isn't, but there are proposals around to change that. Discussion: https://postgr.es/m/16035-456e6e69ebfd4374@postgresql.org
2019-10-25Reset statement_timeout between queries of a multi-query string.Tom Lane
Historically, we started the timer (if StatementTimeout > 0) at the beginning of a simple-Query message and usually let it run until the end, so that the timeout limit applied to the entire query string, and intra-string changes of the statement_timeout GUC had no effect. But, confusingly, a COMMIT within the string would reset the state and allow a fresh timeout cycle to start with the current setting. Commit f8e5f156b changed the behavior of statement_timeout for extended query protocol, and as an apparently-unintended side effect, a change in the statement_timeout GUC during a multi-statement simple-Query message might have an effect immediately --- but only if it was going from "disabled" to "enabled". This is all pretty confusing, not to mention completely undocumented. Let's change things so that the timeout is always reset between queries of a multi-query string, whether they're transaction control commands or not. Thus the active timeout setting is applied to each query in the string, separately. This costs a few more cycles if statement_timeout is active, but it provides much more intuitive behavior, especially if one changes statement_timeout in one of the queries of the string. Also, add something to the documentation to explain all this. Per bug #16035 from Raj Mohite. Although this is a bug fix, I'm hesitant to back-patch it; conceivably somebody has worked out the old behavior and is depending on it. (But note that this change should make the behavior less restrictive in most cases, since the timeout will now be applied to shorter segments of code.)

2019-10-25Handle interrupts within a transaction context in REINDEX CONCURRENTLYMichael Paquier
Phases 2 (building the new index) and 3 (validating the new index) checked for interrupts outside a transaction context, having as consequence to not release session-level locks taken on the parent relation and the old and new indexes processed. This could for example be triggered with statement_timeout and a bad timing, and would issue confusing error messages when shutting down the session still holding the locks (note that an assertion failure would be triggered first), on top of more issues with concurrent sessions trying to take a lock that would interfere with the SHARE UPDATE EXCLUSIVE locks hold here. This moves all the interruption checks inside a transaction context. Note that I have manually tested all interruptions to make sure that invalid indexes can be cleaned up properly. Partition indexes still have issues on their own with some missing dependency handling, which will be dealt with in a follow-up patch.

2019-10-23Acquire properly session-level lock on new index in REINDEX CONCURRENTLYMichael Paquier
In the first transaction run for REINDEX CONCURRENTLY, a thinko in the existing logic caused two session locks to be taken on the old index, causing the session lock on the newly-created index to be missed.

2019-10-21Select CFLAGS_SL at configure time, not in platform-specific Makefiles.Tom Lane
Move the platform-dependent logic that sets CFLAGS_SL from src/makefiles/Makefile.foo to src/template/foo, so that the value is determined at configure time and thus is available while running configure's tests. On a couple of platforms this might save a few microseconds of build time by eliminating a test that make otherwise has to do over and over. Otherwise it's pretty much a wash for build purposes; in particular, this makes no difference to anyone who might be overriding CFLAGS_SL via a make option. This patch in itself does nothing with the value and thus should not change any behavior, though you'll probably have to re-run configure to get a correctly updated Makefile.global. We'll use the new configure variable in a follow-on patch. Per gripe from Kyotaro Horiguchi. Back-patch to all supported branches, because the follow-on patch is a portability bug fix.

2019-10-18Fix failure of archive recovery with recovery_min_apply_delay enabled.Fujii Masao
recovery_min_apply_delay parameter is intended for use with streaming replication deployments. However, the document clearly explains that the parameter will be honored in all cases if it's specified. So it should take effect even if in archive recovery. But, previously, archive recovery with recovery_min_apply_delay enabled always failed, and caused assertion failure if --enable-caasert is enabled. The cause of this problem is that; the ownership of recoveryWakeupLatch that recovery_min_apply_delay uses was taken only when standby mode is requested. So unowned latch could be used in archive recovery, and which caused the failure. This commit changes recovery code so that the ownership of recoveryWakeupLatch is taken even in archive recovery. Which prevents archive recovery with recovery_min_apply_delay from failing. Back-patch to v9.4 where recovery_min_apply_delay was added.

Backpatch all the way to 9.4, where the format for pg_catalog.line data type changed. Author: Tomas Vondra Backpatch-to: 9.4- Discussion: https://postgr.es/m/16045-673e8fa6b5ace196%40postgresql.org
2019-10-16Replace alter_table.sql test usage of event triggers.Andres Freund
The test in 93765bd956b added an event trigger to ensure that the tested table rewrites do not get optimized away (as happened in the past). But doing so would require running the tests in isolation, as otherwise the trigger might also fire in concurrent sessions, causing test failures there.

2019-10-16Remove obsolete collation test.Thomas Munro
The previous commit forgot to remove this test, which no longer holds on all systems.
2019-10-16Use libc version as a collation version on glibc systems.Thomas Munro
Using glibc's version string to detect potential collation definition changes is not 100% reliable, but it's better than nothing. Currently this affects only collations explicitly provided by "libc". More work will be needed to handle the default collation.

2019-10-15Fix CLUSTER on expression indexes.Andres Freund
Since the introduction of different slot types, in 1a0586de3657, we create a virtual slot in tuplesort_begin_cluster(). While that looks right, it unfortunately doesn't actually work, as ExecStoreHeapTuple() is used to store tuples in the slot. Unfortunately no regression tests for CLUSTER on expression indexes existed so far. Fix the slot type, and add bare bones tests for CLUSTER on expression indexes.

2019-10-15Correct reference to pg_catalog.regtype in pg_upgrade queryTomas Vondra
The recursive CTE added in 0ccfc28223 referenced pg_catalog.regtype, without the schema part, unlike all other queries in pg_upgrade. Backpatch-to: 12
