It failed to set the archive_command as it desired because of a syntax
problem. Oversight in commit 90bcc7c2db.
This bug doesn't cause the test to fail, because the test only checks
pg_rewind's output messages, not the actual outcome (and the outcome in
both cases is that the file is kept, not deleted). But in either case
the message about the file being kept is there, so it's hard to get
excited about doing much more.

Previously, in unlucky cases, it was possible for pg_rewind to remove
certain WAL segments from the rewound demoted primary. In particular
this happens if those files have been marked for archival (i.e., their
.ready files were created) but not yet archived; the newly promoted node
no longer has such files because of them having been recycled, but they
are likely critical for recovery in the demoted node. If pg_rewind
removes them, recovery is not possible anymore.
Fix this by maintaining a hash table of files in this situation in the
scan that looks for a checkpoint, which the decide_file_actions phase
can consult so that it knows to preserve them.
Backpatch to 14. The problem also exists in 13, but that branch was not
blessed with commit eb00f1d4bf, so this patch is difficult to apply
there. Users of older releases will just have to continue to be extra
careful when rewinding.

Because in the 18 cycle we turned checksums on by default with commit
04bec894a0, and pg_upgrade fails if the setting doesn't match in old

if the old version is older than 18. Fix the script so that it creates

We now create contype='n' pg_constraint rows for not-null constraints on
user tables. Only one such constraint is allowed for a column.
We propagate these constraints to other tables during operations such as
adding inheritance relationships, creating and attaching partitions and
creating tables LIKE other tables. These related constraints mostly
follow the well-known rules of conislocal and coninhcount that we have
for CHECK constraints, with some adaptations: for example, as opposed to
CHECK constraints, we don't match not-null ones by name when descending
a hierarchy to alter or remove it, instead matching by the name of the
column that they apply to. This means we don't require the constraint
names to be identical across a hierarchy.
The inheritance status of these constraints can be controlled: now we
can be sure that if a parent table has one, then all children will have
it as well. They can optionally be marked NO INHERIT, and then children
are free not to have one. (There's currently no support for altering a
NO INHERIT constraint into inheriting down the hierarchy, but that's a
desirable future feature.)
This also opens the door for having these constraints be marked NOT
VALID, as well as allowing UNIQUE+NOT NULL to be used for functional
dependency determination, as envisioned by commit e49ae8d3bc. It's
likely possible to allow DEFERRABLE constraints as followup work, as
well.
psql shows these constraints in \d+, though we may want to reconsider if
this turns out to be too noisy. Earlier versions of this patch hid
constraints that were on the same columns of the primary key, but I'm
not sure that that's very useful. If clutter is a problem, we might be
better off inventing a new \d++ command and not showing the constraints
in \d+.
For now, we omit these constraints on system catalog columns, because
they're unlikely to achieve anything.
The main difference to the previous attempt at this (b0e96f3119) is
that we now require that such a constraint always exists when a primary
key is in the column; we didn't require this previously which had a
number of unpalatable consequences. With this requirement, the code is
easier to reason about. For example:
- We no longer have "throwaway constraints" during pg_dump. We needed
those for the case where a table had a PK without a not-null
underneath, to prevent a slow scan of the data during restore of the
PK creation, which was particularly problematic for pg_upgrade.
- We no longer have to cope with attnotnull being set spuriously in
case a primary key is dropped indirectly (e.g., via DROP COLUMN).

This patch builds on the work done in commit 745217a051 by enabling the
replication of generated columns alongside regular column changes through
a new publication parameter: publish_generated_columns.
Example usage:
CREATE PUBLICATION pub1 FOR TABLE tab_gencol WITH (publish_generated_columns = true);
The column list takes precedence. If the generated columns are specified
in the column list, they will be replicated even if
'publish_generated_columns' is set to false. Conversely, if generated
columns are not included in the column list (assuming the user specifies a
column list), they will not be replicated even if
'publish_generated_columns' is true.

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.

Previously, per-script statistics were never output when all
transactions failed due to serialization or deadlock errors. However,
it is reasonable to report such information if there are ones even
when there are no successful transaction since these failed
transactions are now objects to be reported.
Meanwhile, if the total number of successful, skipped, and failed
transactions is zero, we don't have to report the number of failed
transactions as similar to the number of skipped transactions, which
avoids to print "NaN%" in lines on failed transaction reports.
Also, the number of transactions in per-script results now includes
skipped and failed transactions. It prevents to print "total of NaN%"
when any transactions are not successfully processed. The number of
transactions actually processed per-script and TPS based on it are now
output explicitly in a separate line.

Rename tab-complete.c to tab-complete.in.c, create the preprocessor
script gen_tabcomplete.pl, and install Makefile/meson.build rules
to create tab-complete.c from tab-complete.in.c. The preprocessor
converts match_previous_words' else-if chain into a switch and
populates tcpatterns[] with the data needed by the driver loop.
The initial HeadMatches/TailMatches/Matches test in each else-if arm
is now performed in a table-driven loop. Where we get a match, the
corresponding switch case is invoked to see if the match succeeds.
(It might not, if there were additional conditions in the original
else-if test.)
The total number of string comparisons done is just about the
same as it was in the previous coding; however, now that we
have table-driven logic underlying the handmade rules, there
is room to improve that. For now I haven't bothered because
tab completion is still plenty fast enough for human use.
If the number of rules keeps increasing, we might someday
need to do more in that area.
The immediate benefit of all this thrashing is that C compilers
frequently don't deal well with long else-if chains. On gcc 8.5.0,
this reduces the compile time of tab-complete.c by about a factor of
four, while MSVC is reported to crash outright with the previous
coding.

Use it to replace the common coding pattern

number of complex if-condition patterns that have to be dealt with
in the next commits in this series.
While here, restructure the *Matches implementation functions so
that the actual work is done in functions that take a char **
array of pattern strings, and the versions taking variadic arguments
are thin wrappers around the array ones. This simplifies the

Commit bf03cfd1 started scanning all available BCP 47 locale names on
Windows. This caused an abort/crash in the Windows runtime library if
the default locale name contained non-ASCII characters, because of our
use of the setlocale() save/restore pattern with "char" strings. After
switching to another locale with a different encoding, the saved name
could no longer be understood, and setlocale() would abort.
"Turkish_Türkiye.1254" is the example from recent reports, but there are
other examples of countries and languages with non-ASCII characters in
their names, and they appear in Windows' (old style) locale names.
To defend against this:
1. In initdb, reject non-ASCII locale names given explicity on the
command line, or returned by the operating system environment with
setlocale(..., ""), or "canonicalized" by the operating system when we
set it.
2. In initdb only, perform the save-and-restore with Windows'
non-standard wchar_t variant of setlocale(), so that it is not subject
to round trip failures stemming from char string encoding confusion.
3. In the backend, we don't have to worry about the save-and-restore
problem because we have already vetted the defaults, so we just have to
make sure that CREATE DATABASE also rejects non-ASCII names in any new
databases. SET lc_XXX doesn't suffer from the problem, but the ban
applies to it too because it uses check_locale(). CREATE COLLATION
doesn't suffer from the problem either, but it doesn't use
check_locale() so it is not included in the new ban for now, to minimize
the change.
Anyone who encounters the new error message should either create a new
duplicated locale with an ASCII-only name using Windows Locale Builder,
or consider using BCP 47 names like "tr-TR". Users already couldn't
initialize a cluster with "Turkish_Türkiye.1254" on PostgreSQL 16+, but
the new failure mode is an error message that explains why, instead of a
crash.

Since backslash is (typically) not special in CSV data, we should
not be treating \. as special either. The server historically did
this to keep CSV and TEXT modes more alike and to support V2 protocol;
but V2 protocol is long dead, and the inconsistency with CSV standards
is annoying. Remove that behavior in CopyReadLineText, and make some
minor consequent code simplifications.
On the client side, we need to fix psql so that it does not check
for \. except when reading data from STDIN (that is, the script
source). We must do that regardless of TEXT/CSV mode or there is
no way to end the COPY short of script EOF. Also, be careful
not to send the \. to the server in that case.
This is a small compatibility break in that other applications
beside psql may need similar adjustment. Also, using an older
version of psql with a v18 server may result in misbehavior
during CSV-mode COPY IN.

Running vacuumdb with a non-superuser while another user has created a
temporary table would lead to a mid-flight permission failure,
interrupting the operation. vacuum_rel() skips temporary relations of
other backends, and it makes no sense for vacuumdb to know about these
relations, so let's switch it to ignore temporary relations entirely.
Adding a qual in the query based on relpersistence simplifies the
generation of its WHERE clause in vacuum_one_database(), per se the
removal of "has_where".

Commit d1379ebf4 carelessly broke printACLColumn for pre-9.4 servers,
by using the cardinality() function which we introduced in 9.4.
We expect psql's describe-related commands to work back to 9.2, so
this is bad. Use the longstanding array_length() function instead.
Per report from Christoph Berg. Back-patch to v17.
