Commit 4f3b38fe2 supposed that complete_from_const() is equivalent to
the one-element-list case of complete_from_list(), but that's not
really true at all. complete_from_const() supposes that the completion
is certain enough to justify wiping out whatever the user typed, while
complete_from_list() will only provide completions that match the
word-so-far.
In practice, given the lame parsing technology used by tab-complete.c,
it's fairly hard to believe that we're *ever* certain enough about
a completion to justify auto-correcting user input that doesn't match.
Hence, remove the inappropriate unification of the two cases.
As things now stand, complete_from_const() is used only for the
situation where we have no matches and we need to keep readline
from applying its default complete-with-file-names behavior.
This (mis?) behavior actually exists much further back, but
I'm hesitant to change it in released branches. It's not too
late for v12, though, especially seeing that the aforesaid
commit is new in v12.
Per gripe from Ken Tanzer.

Don't think that the context "UPDATE tab SET var =" is a GUC-setting
command.
If we have "SET var =" but the "var" is not a known GUC variable,
don't offer any completions. The most likely explanation is that
we've misparsed the context and it's not really a GUC-setting command.
Per gripe from Ken Tanzer. Back-patch to 9.6. The issue exists
further back, but before 9.6 the code looks very different and it
doesn't actually know whether the "var" name matches anything,
so I desisted from trying to fix it.

The previous rule was "primary key (if any) first, then other unique
indexes in name order, then all other indexes in name order".
But the preference for unique indexes seems a bit obsolete since the
introduction of exclusion constraints. It's no longer the case
that unique indexes are the only ones that constrain what data can
be in the table, and it's hard to see what other rationale there is
for separating out unique indexes. Other new features like the
possibility for some indexes to be INVALID (hence, not constraining
anything) make this even shakier.
Hence, simplify the sort order to be "primary key (if any) first,
then all other indexes in name order".
No documentation change, since this was never documented anyway.
A couple of existing regression test cases change output, though.

Up to now, pg_regress --config-auth had a hard-wired assumption
that the target cluster uses the default bootstrap superuser name.
pg_dump's 010_dump_connstr.pl TAP test uses non-default superuser
names, and was klugily getting around the restriction by listing
the desired superuser name as a role to "create". This is pretty
confusing (or at least, it confused me). Let's make it clearer by
allowing --config-auth mode to be told the bootstrap superuser name.
Repurpose the existing --user switch for that, since it has no
other function in --config-auth mode.
Per buildfarm. I don't have an environment at hand in which I can
test this fix, but the buildfarm should soon show if it works.

In commit 18555b132 we tentatively established a rule that regression
tests should use names containing "regression" for databases, and names
starting with "regress_" for all other globally-visible object names, so
as to circumscribe the side-effects that "make installcheck" could have on
an existing installation. However, no enforcement mechanism was created,
so it's unsurprising that some new violations have crept in since then.
In fact, a whole new *category* of violations has crept in, to wit we now
also have globally-visible subscription and replication origin names, and
"make installcheck" could very easily clobber user-created objects of
those types. So it's past time to do something about this.
This commit sanitizes the tests enough that they will pass (i.e. not
generate any visible warnings) with the enforcement mechanism I'll add
in the next commit. There are some TAP tests that still trigger the
warnings, but the warnings do not cause test failure. Since these tests
do not actually run against a pre-existing installation, there's no need
to worry whether they could conflict with user-created objects.
The problem with rolenames.sql testing special role names like "user"
is still there, and is dealt with only very cosmetically in this patch
(by hiding the warnings :-(). What we actually need to do to be safe is
to take that test script out of "make installcheck" altogether, but that
seems like material for a separate patch.

tzdb 2019a made "UCT" a link to the "UTC" zone rather than a separate
zone with its own abbreviation. Unfortunately, our code for choosing a
timezone in initdb has an arbitrary preference for names earlier in
the alphabet, and so it would choose the spelling "UCT" over "UTC"
when the system is running on a UTC zone.
Commit 23bd3cec6 was backpatched in order to address this issue, but
that code helps only when /etc/localtime exists as a symlink, and does
nothing to help on systems where /etc/localtime is a copy of a zone
file (as is the standard setup on FreeBSD and probably some other
platforms too) or when /etc/localtime is simply absent (giving UTC as
the default).
Accordingly, add a preference for the spelling "UTC", such that if
multiple zone names have equally good content matches, we prefer that
name before applying the existing arbitrary rules. Also add a slightly
lower preference for "Etc/UTC"; lower because that preserves the
previous behaviour of choosing the shorter name, but letting us still
choose "Etc/UTC" over "Etc/UCT" when both exist but "UTC" does
not (not common, but I've seen it happen).
Backpatch all the way, because the tzdb change that sparked this issue
is in those branches too.
Fixes some problems introduced by 6e5f8d489acc:
* When reusing conninfo data from the previous connection in \connect,
the host address should only be reused if it was specified as
hostaddr; if it wasn't, then 'host' is resolved afresh. We were
reusing the same IP address, which ignores a possible DNS change
as well as any other addresses that the name resolves to than the
one that was used in the original connection.
* PQhost, PQhostaddr: Don't present user-specified hostaddr when we have
an inet_net_ntop-produced equivalent address. The latter has been
put in canonical format, which is cleaner (so it produces "127.0.0.1"
when given "host=2130706433", for example).
* Document the hostaddr-reusing aspect of \connect.
* Fix some code comments

Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025d (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.
This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8 in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure
to restore serial columns). They were reverted. This recapitulation
commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b14 to master.

Previously, running pg_waldump with an invalid option (pg_waldump
--foo) would print the help output and exit successfully. This was
because it tried to process the option letter '?' as a normal option,
but that letter is used by getopt() to report an invalid option.
To fix, process help and version options separately, like we do
everywhere else. Also add a basic test suite for pg_waldump and run
the basic option handling tests, which would have caught this.

We have a longstanding project convention that all .h files should
be includable with no prerequisites other than postgres.h. This is
tested/relied-on by cpluspluscheck. However, cpluspluscheck has not
historically been applied to most headers outside the src/include
tree, with the predictable consequence that some of them don't work.
Fix that, usually by adding missing #include dependencies.
The change in printf_hack.h might require some explanation: without
it, my C++ compiler whines that the function is unused. There's
not so many call sites that "inline" is going to cost much, and
besides all the callers are in test code that we really don't care
about the size of.
There's no actual bugs being fixed here, so I see no need to back-patch.

When this suite runs installcheck, redirect file creations from
src/test/regress to src/bin/pg_upgrade/tmp_check/regress. This closes a
race condition in "make -j check-world". If the pg_upgrade suite wrote
to a given src/test/regress/results file in parallel with the regular
src/test/regress invocation writing it, a test failed spuriously. Even
without parallelism, in "make -k check-world", the suite finishing
second overwrote the other's regression.diffs. This revealed test
"largeobject" assuming @abs_builddir@ is getcwd(), so fix that, too.
Buildfarm client REL_10, released fifty-four days ago, supports saving
regression.diffs from its new location. When an older client reports a
pg_upgradeCheck failure, it will no longer include regression.diffs.

This uses a method similar to 68a7c24f and now b8c6014 (applied for
database creation), which guarantees that GRANT commands using the WITH
GRANT OPTION are dumped in a way so as cascading dependencies are
respected. Note that tablespaces do not have support for initial
privileges via pg_init_privs, so the same method needs to be applied
again. It would be nice to merge all the logic generating ACL queries
in dumps under the same banner, but this requires extending the support
of pg_init_privs to objects that cannot use it yet, so this is left as
future work.

The use of "set -x" to echo a subset of the test's commands might've
been a good idea during development of this test, but it's been stable
for long enough now that the extra output isn't very useful. Also
our project expectations have been trending towards less output in
non-error cases; the fact that "set -x" produces output on stderr
is particularly annoying from that standpoint. So get rid of it.
Also, pass "-A trust" to initdb explicitly so that it won't issue
a warning about "trust" being an insecure default. This matches
what the TAP tests have done for a long time, and again gets rid
of some noise on stderr.
