Modify the new event loop code from commit 7389aad6 so that it checks
for work requested by signal handlers even if it doesn't see a latch
event yet.
This gives priority to shutdown and reload requests where the latch will
be reported later in the event array, or in a later call to
WaitEventSetWait(), due to scheduling details. In particular, this
guarantees that a SIGHUP-then-connect sequence (as seen in
authentication tests) causes the postmaster to process the reload before
accepting the connection. If the WaitEventSetWait() call saw the socket
as ready, and the reload signal was generated before the connection,
then the latest time the signal handler should be able to run is after
poll/epoll_wait/kevent returns but before we check the
pending_pm_reload_request flag.
While here, also shift the handling of child exit below reload requests,
per Tom Lane's observation that that might start new processes, so we
should make sure we pick up new settings first.
This probably explains the one-off failure of build farm animal
malleefowl.

This makes two small changes that will improve pgindent's usefulness in
a git hook. First, it looks for the exclude file relative to the current
directory. And second, it applies the filters to filenames given on the
command line as well as those found in a directory sweep.
It might prove necessary to make further efforts to find the exclude
file, and even to allow multiple exclude files, but for now this should
be enough for most purposes.

Previously, a CREATEROLE user without SUPERUSER could not alter
REPLICATION users in any way, and could not set the BYPASSRLS
attribute. However, they could manipulate the CREATEDB property
even if they themselves did not possess it.
With this change, a CREATEROLE user without SUPERUSER can set or
clear the REPLICATION, BYPASSRLS, or CREATEDB property on a new
role or a role that they have rights to manage if and only if
that property is set for their own role.
This implements the standard idea that you can't give permissions
you don't have (but you can give the ones you do have). We might
in the future want to provide more powerful ways to constrain
what a CREATEROLE user can do - for example, to limit whether
CONNECTION LIMIT can be set or the values to which it can be set -
but that is left as future work.

The drop database command waits for the logical replication sync worker to
accept ProcSignalBarrier and the worker's slot creation waits for the drop
database to finish which leads to a deadlock. This happens because the
tablesync worker holds interrupts while creating a slot.
We prevent cancel/die interrupts while creating a slot in the table sync
worker because it is possible that before the server finishes this
command, a concurrent drop subscription happens which would complete
without removing this slot and that leads to the slot existing until the
end of walsender. However, the slot will eventually get dropped at the
walsender exit time, so there is no danger of the dangling slot.
This patch reallows cancel/die interrupts while creating a slot and
modifies the test to wait for slots to become zero to prevent finding an
ephemeral slot.
The reported hang doesn't happen in PG14 as the drop database starts to
wait for ProcSignalBarrier with PG15 (commits 4eb2176318 and e2f65f4255)
but it is good to backpatch this till PG14 as it is not a good idea to
prevent interrupts during a network call that could block indefinitely.

In contrast to the changes to dblink and postgres_fdw, this does not fix a
bug, as libpqwalreceiver did already process interrupts.
Besides reducing code duplication, the conversion leads to libpqwalreceiver
now using reserving file descriptors for libpq connections. While not strictly

logical replication, where it does seem more important.

When libpqrcv_connect (also known as walrcv_connect()) failed, it leaked the
libpq connection. In most paths that's fairly harmless, as the calling process
will exit soon after. But e.g. CREATE SUBSCRIPTION could lead to a somewhat

Fix by releasing resources, including the libpq connection, on error.
Add a test exercising the error code path. To make it reliable and safe, the
test tries to connect to port=-1, which happens to fail during connection

The motivation for this change is that when pg_dump dumps a
partitioned index that's marked REPLICA IDENTITY, it generates a
command sequence that applies REPLICA IDENTITY before the partitioned
index has been marked valid, causing restore to fail. We could
perhaps change pg_dump to not do it like that, but that would be
difficult and would not fix existing dump files with the problem.
There seems to be very little reason for the backend to disallow
this anyway --- the code ignores indisreplident when the index
isn't valid --- so instead let's fix it by allowing the case.
Commit 9511fb37a previously expressed a concern that allowing
indisreplident to be set on invalid indexes might allow us to
wind up in a situation where a table could have indisreplident
set on multiple indexes. I'm not sure I follow that concern
exactly, but in any case the only way that could happen is because
relation_mark_replica_identity is too trusting about the existing set
of markings being valid. Let's just rip out its early-exit code path
(which sure looks like premature optimization anyway; what are we
doing expending code to make redundant ALTER TABLE ... REPLICA
IDENTITY commands marginally faster and not-redundant ones marginally
slower?) and fix it to positively guarantee that no more than one
index is marked indisreplident.
The pg_dump failure can be demonstrated in all supported branches,
so back-patch all the way. I chose to back-patch 9511fb37a as well,
just to keep indisreplident handling the same in all branches.

When the length was too short, the server read outside the allocation.
That yielded the same log noise as sending the correct length with

memory layout and the general lack of diversity in memory layouts at the

Until now we used struct timespec for instr_time on all platforms but
windows. Using struct timespec causes a fair bit of memory (struct timeval is
16 bytes) and runtime overhead (much more complicated additions). Instead we
can convert the time to nanoseconds in INSTR_TIME_SET_CURRENT(), making the
remaining operations cheaper.
Representing time as int64 nanoseconds provides sufficient range, ~292 years
relative to a starting point (depending on clock source, relative to the unix
epoch or the system's boot time). That'd not be sufficient for calendar time
stored on disk, but is plenty for runtime interval time measurement.
On windows instr_time already is represented as cycles. It might make sense to
represent time as cycles on other platforms as well, as using cycle
acquisition instructions like rdtsc directly can reduce the overhead of time
acquisition substantially. This could be done in a fairly localized manner as
the code stands after this commit.
Because the windows and non-windows paths are now more similar, use a common
set of macros. To make that possible, most of the use of LARGE_INTEGER had to
be removed, which looks nicer anyway.
To avoid users of the API relying on the integer representation, we wrap the
64bit integer inside struct struct instr_time.

While pg_hba.conf has support for non-literal username matches, and
this commit extends the capabilities that are supported for the
PostgreSQL user listed in an ident entry part of pg_ident.conf, with
support for:
1. The "all" keyword, where all the requested users are allowed.
2. Membership checks using the + prefix.
3. Using a regex to match against multiple roles.
1. is a feature that has been requested by Jelte Fennema, 2. something
that has been mentioned independently by Andrew Dunstan, and 3. is
something I came up with while discussing how to extend the first one,
whose implementation is facilitated by 8fea868.
This allows matching certain system users against many different
postgres users with a single line in pg_ident.conf. Without this, one
would need one line for each of the postgres users that a system user
can log in as, which can be cumbersome to maintain.
Tests are added to the TAP test of peer authentication to provide
coverage for all that.
Note that this introduces a set of backward-incompatible changes to be
able to detect the new patterns, for the following cases:
- A role named "all".
- A role prefixed with '+' characters, which is something that would not
have worked in HBA entries anyway.
- A role prefixed by a slash character, similarly to 8fea868.
Any of these can be still be handled by using quotes in the Postgres
role defined in an ident entry.
A huge advantage of this change is that the code applies the same checks
for the Postgres roles in HBA and ident entries, via the common routine
check_role().
**This compatibility change should be mentioned in the release notes.**

This adjusts a few places which were appending a string constant
containing spaces onto a StringInfo. We have appendStringInfoSpaces for
that job, so let's use that instead.
For the change to jsonb.c's add_indent() function, appendStringInfoString
was being called inside a loop to append 4 spaces on each loop. This
meant that enlargeStringInfo would get called once per loop. Here it
should be much more efficient to get rid of the loop and just calculate
the number of spaces with "level * 4" and just append all the spaces in
one go.
Here we additionally adjust the appendStringInfoSpaces function so it
makes use of memset rather than a while loop to apply the required spaces
to the StringInfo. One of the problems with the while loop was that it
was incrementing one variable and decrementing another variable once per
loop. That's more work than what's required to get the job done. We may
as well use memset for this rather than trying to optimize the existing
loop. Some testing has shown memset is faster even for very small sizes.

This patch largely reverts what I did in commits c9b0c678d and
78e73e875. The maximum cover length limit that I added in 78e73e875
(to band-aid over c9b0c678d's performance issues) creates too many
user-visible behavior discrepancies, as complained of for example in
bug #17691. The real problem with hlCover() is not what I thought
at the time, but more that it seems to have been designed with only
AND tsquery semantics in mind. It doesn't work quite right for OR,
and even less so for NOT or phrase queries. However, we can improve
that situation by building a variant of TS_execute() that returns a
list of match locations. We already get an ExecPhraseData struct
representing match locations for the primitive case of a simple match,
as well as one for a phrase match; we just need to add some logic to
combine these for AND and OR operators. The result is a list of
ExecPhraseDatas, which hlCover can regard as having simple AND
semantics, so that its old algorithm works correctly.
There's still a lot not to like about ts_headline's behavior, but
I think the remaining issues have to do with the heuristics used
in mark_hl_words and mark_hl_fragments (which, likewise, were not
revisited when phrase search was added). Improving those is a task
for another day.

This is wrong since 88e9823, that has switched the WAL sizing

GUC checkpoint_segments, on reload, for example, and it controls the
timing of checkpoints depending on the volume of WAL generated.
Most users tend to leave checkpoint_completion_target at 0.9 to smooth
