The TAP tests whose ok() calls are changed in this commit were relying
on perl operators, rather than equivalents available in Test::More. For
example, rather than the following:
ok($data =~ qr/expr/m, "expr matching");
ok($data !~ qr/expr/m, "expr not matching");
The new test code uses this equivalent:
like($data, qr/expr/m, "expr matching");
unlike($data, qr/expr/m, "expr not matching");
A huge benefit of the new formulation is that it is possible to know
about the values we are checking if a failure happens, making debugging
easier, should the test runs happen in the buildfarm, in the CI or
locally.
This change leads to more test code overall as perltidy likes to make
the code pretty the way it is in this commit.

040_pg_createsubscriber has been calling safe_psql(), that returns the
result of a SQL query, with ok() without checking the result generated
(in this case 't', for a number of publications).
The outcome of the tests is currently not impacted by this change.
However, it could be possible that the test fails to detect future
issues if the query results become different.
The test is rewritten so as the number of publications is checked. This
is not the fix suggested originally by the author, but this is more
reliable in the long run.

pg_createsubscriber is documented as requiring the same major version as
the target clusters. Attempting to use this tool on a cluster where the
control file version read does not match with the version compiled with
would lead to the following error message:
pg_createsubscriber: error: control file appears to be corrupt
This is confusing as the control file is correct: only the version
expected does not match. This commit integrates pg_createsubscriber
with the facility added by cd0be131ba6f, where the contents of
PG_VERSION are read and compared with the value of PG_MAJORVERSION_NUM
expected by the tool. This puts pg_createsubscriber in line with the
documentation, with a better error message when the version does not
match.

This reverts commit 74ac377d75135e02064fc4427bec401277b4f60c.
The previous change contained a misconception about how publications
are cleaned up on the subscriber. The newly added log message could
confuse users, particularly when running pg_createsubscriber with
--dry-run - users would see a "dropping publication" message
immediately followed by a "no publications found" message.

The creation of a replication slot done in a specific database on a
publisher was logged twice, with the second log not mentioning the
database where the slot creation happened. This commit removes the
information logged after a slot has been successfully created, moving
the information about the publisher from the second to the first log.
Note that failing a slot creation is also logged, so there is no loss of
information.

Previously, the tool could replay the same transaction twice, once during
recovery, then again during replication after the subscriber was set up.
This occurred because the same recovery_target_lsn was used both to
finalize recovery and to start replication. If
recovery_target_inclusive = true, the transaction at that LSN would be
applied during recovery and then sent again by the publisher leading to
duplication.
To prevent this, we now set recovery_target_inclusive = false. This
ensures the transaction at recovery_target_lsn is not reapplied during
recovery, avoiding duplication when replication begins.

This commit standardizes the output format for LSNs to ensure consistent
representation across various tools and messages. Previously, LSNs were
inconsistently printed as `%X/%X` in some contexts, while others used
zero-padding. This often led to confusion when comparing.
To address this, the LSN format is now uniformly set to `%X/%08X`,
ensuring the lower 32-bit part is always zero-padded to eight
hexadecimal digits.

The previous minimum was to maintain support for Python 3.5, but we
now require Python 3.6 anyway (commit 45363fca637), so that reason is
obsolete. A small raise to Meson 0.57 allows getting rid of a fair
amount of version conditionals and silences some future-deprecated
warnings.
With the version bump, the following deprecation warnings appeared and
are fixed:
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
It turns out that meson 0.57.0 and 0.57.1 are buggy for our use, so
the minimum is actually set to 0.57.2. This is specific to this
version series; in the future we won't necessarily need to be this
precise.

This commit renames the pg_recvlogical options --two-phase and
--failover to --enable-two-phase and --enable-failover, respectively.
The new names distinguish these enabling options from action options
like --start and --create-slot, while clearly indicating their purpose
to enable specific logical slot features.
The option --failover is new in PostgreSQL 18 (commit cf2655a9029), so
no compatibility break there. The option --two-phase has existed
since PostgreSQL 15 (commit cda03cfed6b), so for compatibility we keep
the old option name --two-phase around as deprecated.
Also note that pg_createsubscriber has acquired an --enable-two-phase
option, so this increases consistency across tools.

Unlike 3fae25cbb, which fixed this issue for code that was new to v18,
this one fixes up instances which exist in the backbranches. We've
historically tried to maintain this standard and if we're going to

The '--all' option indicates that the tool queries the source server
(publisher) for all databases and creates subscriptions on the target
server (subscriber) for databases with matching names. Without this user
needs to explicitly specify all databases by using -d option for each
database.
This simplifies converting a physical standby to a logical subscriber,
particularly during upgrades.
The options '--database', '--publication', '--subscription', and
'--replication-slot' cannot be used when '--all' is specified.

This new option instructs initdb to skip synchronizing any files
in database directories, the database directories themselves, and
the tablespace directories, i.e., everything in the base/
subdirectory and any other tablespace directories. Other files,
such as those in pg_wal/ and pg_xact/, will still be synchronized
unless --no-sync is also specified. --no-sync-data-files is
primarily intended for internal use by tools that separately ensure
the skipped files are synchronized to disk. A follow-up commit
will use this to help optimize pg_upgrade's file transfer step.
The --sync-method=fsync implementation of this option makes use of
a new exclude_dir parameter for walkdir(). When not NULL,
exclude_dir specifies a directory to skip processing. The
--sync-method=syncfs implementation of this option just skips
synchronizing the non-default tablespace directories. This means
that initdb will still synchronize some or all of the database
files, but there's not much we can do about that.

When pg_recvlogical was introduced in 9.4, the --dbname option was not
required for --drop-slot. Without it, pg_recvlogical --drop-slot connected
using a replication connection (not tied to a specific database) and
was able to drop both physical and logical replication slots, similar to
pg_receivewal --drop-slot.
However, commit 0c013e08cfb unintentionally changed this behavior in 9.5,
making pg_recvlogical always check whether it's connected to a specific
database and fail if it's not. This change was expected for --create-slot
and --start, which handle logical replication slots and require a database
connection, but it was unnecessary for --drop-slot, which should work with
any replication connection. As a result, --dbname became a required option
for --drop-slot.
This commit removes that restriction, restoring the original behavior and
allowing pg_recvlogical --drop-slot to work without specifying --dbname.
Although this issue originated from an unintended change, it has existed
for a long time without complaints or bug reports, and the documentation
never explicitly stated that --drop-slot should work without --dbname.
Therefore, the change is not treated as a bug fix and is applied only to
master.

for all subscriptions during their creation.
Note that even without this option users can enable the two_phase option
for the subscriptions created by pg_createsubscriber. However, it requires

users.
When two-phase commit is enabled, prepared transactions are sent to the
subscriber at the time of 'PREPARE TRANSACTION', and they are processed as
two-phase transactions on the subscriber as well. If disabled, prepared
transactions are sent only when committed and are processed immediately by
the subscriber.

This commit introduces idle_replication_slot_timeout GUC that allows
inactive slots to be invalidated at the time of checkpoint. Because
checkpoints happen checkpoint_timeout intervals, there can be some lag
between when the idle_replication_slot_timeout was exceeded and when the
slot invalidation is triggered at the next checkpoint. To avoid such lags,
users can force a checkpoint to promptly invalidate inactive slots.
Note that the idle timeout invalidation mechanism is not applicable for
slots that do not reserve WAL or for slots on the standby server that are
synced from the primary server (i.e., standby slots having 'synced' field
'true'). Synced slots are always considered to be inactive because they
don't perform logical decoding to produce changes.
The slots can become inactive for a long period if a subscriber is down
due to a system error or inaccessible because of network issues. If such a
situation persists, it might be more practical to recreate the subscriber
rather than attempt to recover the node and wait for it to catch up which
could be time-consuming.
Then, external tools could create replication slots (e.g., for migrations
or upgrades) that may fail to remove them if an error occurs, leaving
behind unused slots that take up space and resources. Manually cleaning
them up can be tedious and error-prone, and without intervention, these
lingering slots can cause unnecessary WAL retention and system bloat.
As the duration of idle_replication_slot_timeout is in minutes, any test
using that would be time-consuming. We are planning to commit a follow up
patch for tests by using the injection point framework.

Coverity complained about possible double free of HandleCopyStream's
"copybuf". AFAICS it's mistaken, but it is easy to see why it's
confused, because management of that buffer is impossibly confusing.
It's unreasonable that HandleEndOfCopyStream frees the buffer in some
cases but not others, updates the caller's state for that in no case,
and has not a single comment about how complicated that makes things.
Let's put all the responsibility for freeing copybuf in the actual
owner of that variable, HandleCopyStream. This results in one more
PQfreemem call than before, but the logic is far easier to follow,
both for humans and machines.
Since this isn't (quite) actually broken, no back-patch.

The correct function documented to free the memory allocated for the
result returned by PQescapeIdentifier() and PQescapeLiteral() is
PQfreemem(). pg_createsubscriber.c relied on pg_free() instead, which
is not incorrect as both do a free() internally, but inconsistent with
the documentation.
While on it, this commit fixes a small memory leak introduced by
4867f8a555ce, as the code of pg_createsubscriber makes this effort.

together. This is particularly useful for the readability of multi-line
command arrays, and there are plenty of them in the TAP tests. Most of
the test code is updated to use this style. Some commands used
parenthesis to show the link, or attached values and options in a single
string. These are updated to use fat commas instead.
- Option names are switched to use their long names, making them more
self-documented. Based on a suggestion by Andrew Dunstan.
- Add some trailing commas after the last item in multi-line arrays,
which is a common perl style.
Not all the places are taken care of, but this covers a very good chunk
of them.

A follow-up patch will adjust the TAP tests to follow a more-structured
format for option lists in commands, that perltidy is able to cope
better with. Putting the tree first in a clean state makes the next
change a bit easier. v20230309 has been used.

walmethods.c used off_t to navigate around a pg_wal.tar file that could
exceed 2GB, which doesn't work on Windows and would fail with misleading
errors. Use pgoff_t instead.
Back-patch to all supported branches.

Sloppy refactoring in commit cca97ce6a caused these programs
to pass dbname = NULL to libpq if there was no "--dbname" switch
on the command line, where before "replication" would be passed.
This didn't break things completely, because the source server doesn't
care about the dbname specified for a physical replication connection.
However, it did cause libpq to fail to match a ~/.pgpass entry that
has "replication" in the dbname field. Restore the previous behavior
of passing "replication".
Also, closer inspection shows that if you do specify a dbname
in the connection string, that is what will be matched to ~/.pgpass,
not "replication". This was the pre-existing behavior so we should
not change it, but the SGML docs were pretty misleading about it.
Improve that.
Per bug #18685 from Toshi Harada. Back-patch to v17 where the
error crept in.

This is a continuation of 17974ec25946. More quotes are applied to
GUC names in error messages and hints, taking care of what seems to be
all the remaining holes currently in the tree for the GUCs.

In the recent commit f80b09bac8, astreamer files were moved to another
directory, but this change was not reflected in nls.mk. This commit
corrects that oversight.

Some code using atol() would not work correctly if sizeof(long)==4:
- src/bin/pg_basebackup/pg_basebackup.c: Would miscount size of a
tablespace over 2 TB.
- src/bin/pg_basebackup/streamutil.c: Would truncate a timeline ID
beyond INT32_MAX.
- src/bin/pg_rewind/libpq_source.c: Would miscount size of files
larger than 2 GB (but this currently cannot happen).
Replace these with atoll().
In one case, the use of atol() did not result in incorrect behavior
but seems inconsistent with related code:
- src/interfaces/ecpg/ecpglib/execute.c: Gratuitous, since it
processes a value from pg_type.typlen, which is int16.
Replace this with atoi().
