Add _lookup_hash and _insert_hash functions for callers that have
already calculated the hash value of the key.
The immediate use case is for hash algorithms that write to disk in
partitions. The hash value can be calculated once, used to perform a
lookup, used to select the partition, then written to the partition
along with the tuple. When the tuple is read back, the hash value does
not need to be recalculated.

This allows simplification of the plan tree in some common usage
patterns: we can get rid of a join to the function RTE.
In principle we could pull up any immutable expression, but restricting
it to Consts avoids the risk that multiple evaluations of the expression
might cost more than we can save. (Possibly this could be improved in
future --- but we've more or less promised people that putting a function
in FROM guarantees single evaluation, so we'd have to tread carefully.)
To do this, we need to rearrange when eval_const_expressions()
happens for expressions in function RTEs. I moved it to
inline_set_returning_functions(), which already has to iterate over
every function RTE, and in consequence renamed that function to
preprocess_function_rtes(). A useful consequence is that
inline_set_returning_function() no longer has to do this for itself,
simplifying that code.
In passing, break out pull_up_simple_subquery's code that knows where
everything that needs pullup_replace_vars() processing is, so that
the new pull_up_constant_function() routine can share it. We'd
gotten away with one-and-a-half copies of that code so far, since
pull_up_simple_values() could assume that a lot of cases didn't apply
to it --- but I don't think pull_up_constant_function() can make any
simplifying assumptions. Might as well make pull_up_simple_values()
use it too.
(Possibly this refactoring should go further: maybe we could share
some of the code to fill in the pullup_replace_vars_context struct?
For now, I left it that the callers fill that completely.)
Note: the one existing test case that this patch changes has to be
changed because inlining its function RTEs would destroy the point
of the test, namely to check join order.

Commit a1c1af2a1 added logic in the deadlock checker to handle lock
grouping, but it was very poorly tested, as evidenced by the bug
fixed in 3420851a2. Add a test case that exercises that a bit better
(and catches the bug --- if you revert 3420851a2, this will hang).
Since it's pretty hard to get parallel workers to take exclusive
regular locks that their parents don't already have, this test operates
by creating a deadlock among advisory locks taken in parallel workers.
To make that happen, we must override the parallel-safety labeling of
the advisory-lock functions, which we do by putting them in mislabeled,
non-inlinable wrapper functions.
We also have to remove the redundant PreventAdvisoryLocksInParallelMode
checks in lockfuncs.c. That seems fine though; if some user accidentally
does what this test is intentionally doing, not much harm will ensue.
(If there are any remaining bugs that are reachable that way, they're
probably reachable in other ways too.)

Since pg_dump doesn't treat the member operators and functions of operator
classes/families (that is, the pg_amop and pg_amproc entries, not the
underlying operators/functions) as separate dumpable objects, it missed
their dependency information. I think this was safe when the code was
designed, because the default object sorting rule emits operators and
functions before opclasses, and there were no dependency types that could
mess that up. However, the introduction of range types in 9.2 broke it:
now a type can have a dependency on an opclass, allowing dependency rules
to push the opclass before the type and hence before custom operators.
Lacking any information showing that it shouldn't do so, pg_dump emitted
the objects in the wrong order.
Fix by teaching getDependencies() to translate pg_depend entries for
pg_amop/amproc rows to look like dependencies for their parent opfamily.
I added a regression test for this in HEAD/v12, but not further back;
life is too short to fight with 002_pg_dump.pl.

The tests collate.icu.utf8 and collate.linux.utf8 were previously only

database, because the error messages in the expected files refer to
that, and they use some non-ASCII characters in the tests. Since
users can select any locale and encoding for the regression test run,
it was not possible to include these tests automatically.
To fix, use psql's \if facility to check various prerequisites such as
platform and the server encoding and quit the tests at the very

maintain alternative expected files for these tests, but they are very
tiny and never need to change after this.

When performing ANALYZE on inheritance trees, we collect two samples for
each relation - one for the relation alone, and one for the inheritance
subtree (relation and its child relations). And then we build statistics
on each sample, so for each relation we get two sets of statistics.
For regular (per-column) statistics this works fine, because the catalog
includes a flag differentiating statistics built from those two samples.
But we don't have such flag in the extended statistics catalogs, and we
ended up updating the same row twice, triggering this error:
ERROR: tuple already updated by self
The simplest solution is to disable extended statistics on inheritance
trees, which is what this commit is doing. In the future we may need to
do something similar to per-column statistics, but that requires adding a
flag to the catalog - and that's not backpatchable. Moreover, the current

When building a list of relations for a parallel processing of a schema
or a database (or just a single-entry list for the non-parallel case
with the database name), the list is allocated and built on-the-fly for
each database processed, leaking after one database-level reindex is
done. This accumulates leaks when processing all databases, and could
become a visible issue with thousands of relations.
This is fixed by introducing a new routine in simple_list.c to free all
the elements in a simple list made of strings or OIDs. The header of
the list may be using a variable declaration or an allocated pointer,
so we don't have a routine to free this part to keep the interface

When copying the definition of an index rebuilt concurrently for the new
entry, the index information was taken directly from the old index using
the relation cache. In this case, predicates and expressions have
some post-processing to prepare things for the planner, which loses some
information including the collations added in any of them.
This inconsistency can cause issues when attempting for example a table
rewrite, and makes the new indexes rebuilt concurrently inconsistent
with the old entries.
In order to fix the problem, fetch expressions and predicates directly
from the catalog of the old entry, and fill in IndexInfo for the new
index with that. This makes the process more consistent with
DefineIndex(), and the code is refactored with the addition of a routine
to create an IndexInfo node.

We had no actual end-to-end test of NOTIFY message delivery. In the

traditionally prints the PID of the sending backend, making the output
unstable. We also have an isolation test script, but it likewise
failed to prove that delivery worked, because isolationtester.c had
no provisions for detecting/reporting NOTIFY messages.
Hence, add such provisions to isolationtester.c, and extend
async-notify.spec to include direct tests of basic NOTIFY functionality.
I also added tests showing that NOTIFY de-duplicates messages normally,
but not across subtransaction boundaries. (That's the historical

If a test sends a notice just before blocking, it's possible on
slow machines for isolationtester to detect the blocked state before
it's consumed the notice. (For this to happen, the notice would have
to arrive after isolationtester has waited for data for 10ms, so on
fast/lightly-loaded machines it's hard to reproduce the failure.)
But, if we have seen the backend as blocked, it's certainly already
sent any notices it's going to send. Therefore, one more round of
PQconsumeInput and PQisBusy should be enough to collect and process
any such notices.
This appears to explain the instability noted in commit ebd499282, so undo
the hack therein to not print notices from insert-conflict-specconflict.

For its entire existence, isolationtester.c has forced client_min_messages
to WARNING, but that seems like a very poor choice of test design. It
should be up to individual test scripts to manage whether they emit notices
and to ensure that the results are stable. (There were no NOTICE messages
in the original set of isolation tests, so this was certainly dead code
when committed, but perhaps it was needed at some earlier point.)
It's possible that the original motivation was due to platform-dependent
variations in the timing of stdout vs. stderr output. That should be
moot since commits 73bcb76b7/6eda3e9c2, but just in case, adjust
isotesterNoticeProcessor to print to stdout not stderr. (stderr seems
like the wrong thing anyway: it should be for error printouts not expected
test output.)
Testing shows that the notices in insert-conflict-specconflict are indeed
a bit timing-unstable on very slow machines, so hide them; maybe we can
improve that later. Also, make the notices in plpgsql-toast a bit less
verbose than the original code would've had them.

pg_timezone_names() tries to avoid showing the "Factory" zone in
the view, mainly because that has traditionally had a very long
"abbreviation" such as "Local time zone must be set--see zic manual page",
so that showing it messes up psql's formatting of the whole view.
Since tzdb version 2016g, IANA instead uses the abbreviation "-00",
which is sane enough that there's no reason to discriminate against it.
On the other hand, it emerges that FreeBSD and possibly other packagers
are so wedded to backwards compatibility that they hack the IANA data
to keep the old spelling --- and not just that old spelling, but even
older spellings that IANA used back in the stone age. This caused the
filter logic to fail to suppress "Factory" at all on such platforms,
though the formatting problem is definitely real in that case.
To solve both problems, get rid of the hard-wired assumption about
exactly what Factory's abbreviation is, and instead reject abbreviations
exceeding 31 characters. This will allow Factory to appear in the view
if and only if it's using the modern abbreviation.
In passing, simplify the code we add to zic.c to support "zic -P"
to remove its now-obsolete hacks to not print the Factory zone's
abbreviation. Unlike pg_timezone_names(), there's no reason for
that code to support old/nonstandard timezone data.

Some platforms create a file named "localtime" in the system
timezone directory, making it a copy or link to the active time
zone file. If Postgres is built with --with-system-tzdata, initdb
will see that file as an exact match to localtime(3)'s behavior,
and it may decide that "localtime" is the most preferred spelling of
the active zone. That's a very bad choice though, because it's
neither informative, nor portable, nor stable if someone changes
the system timezone setting. Extend the preference logic added by
commit e3846a00c so that we will prefer any other zone file that
matches localtime's behavior over "localtime".
On the same logic, also discriminate against "posixrules", which
is another not-really-a-zone file that is often present in the
timezone directory. (Since we install "posixrules" but not
"localtime", this change can affect the behavior of Postgres
with or without --with-system-tzdata.)
Note that this change doesn't prevent anyone from choosing these
pseudo-zones if they really want to (i.e., by setting TZ for initdb,
or modifying the timezone GUC later on). It just prevents initdb
from preferring these zone names when there are multiple matches to
localtime's behavior.

Since 15d8f8312 we assert that - and since 7ef04e4d2c, 4da597edf1
rely on - the slot type for an expression's
ecxt_{outer,inner,scan}tuple not changing, unless explicitly flagged
as such. That allows to either skip deforming (for a virtual tuple
slot) or optimize the code for JIT accelerated deforming
appropriately (for other known slot types).
This assumption was sometimes violated for grouping sets, when
nodeAgg.c internally uses tuplesorts, and the child node doesn't
return a TTSOpsMinimalTuple type slot. Detect that case, and flag that
the outer slot might not be "fixed".
It's probably worthwhile to optimize this further in the future, and
more granularly determine whether the slot is fixed. As we already
instantiate per-phase transition and equal expressions, we could
cheaply set the slot type appropriately for each phase. But that's a
separate change from this bugfix.
This commit does include a very minor optimization by avoiding to
create a slot for handling tuplesorts, if no such sorts are
performed. Previously we created that slot unnecessarily in the common
case of computing all grouping sets via hashing. The code looked too
confusing without that, as the conditions for needing a sort slot and
flagging that the slot type isn't fixed, are the same.

libpq failed to ignore Windows-style newlines in connection service files.
This normally wasn't a problem on Windows itself, because fgets() would
convert \r\n to just \n. But if libpq were running inside a program that
changes the default fopen mode to binary, it would see the \r's and think
they were data. In any case, it's project policy to ignore \r in text
files unconditionally, because people sometimes try to use files with
DOS-style newlines on Unix machines, where the C library won't hide that
from us.
Hence, adjust parseServiceFile() to ignore \r as well as \n at the end of

whitespace, to match what it's always done with leading whitespace.
In HEAD, also run around and fix up everyplace where we have

on Windows can return \r\n. (The Windows-specific code in pipe_read_line

If the user creates a deferred constraint in a partition, and in a
transaction they cause the constraint's trigger execution to be deferred
until commit time *and* drop the constraint, then when commit time comes
the queued trigger will fail to run because the trigger object will have
been dropped.
This is explained because when a constraint gets dropped in a
partitioned table, the recursion to drop the ones in partitions is done
by the dependency mechanism, not by ALTER TABLE traversing the recursion
tree as in all other cases. In the non-partitioned case, this problem
is avoided by checking that the table is not "in use" by alter-table;
other alter-table subcommands that recurse to partitions do that check
for each partition. But the dependency mechanism doesn't have a way to
do that. Fix the problem by applying the same check to all partitions
during ALTER TABLE's "prep" phase, which correctly raises the necessary
