Fix issues with describe queries of extended statistics in psql
This addresses some problems in the describe queries used for extended
statistics:
- Two schema qualifications for the text type were missing for \dX.
- The list of extended statistics listed for a table through \d was

- A couple of aliases were not used in \d. These are removed.

Respect permissions within logical replication.
Prevent logical replication workers from performing insert, update,

Prevent subscription owners from circumventing row-level security by
forbidding replication into tables with row-level security policies
which the subscription owner is subject to, without regard to whether
the policy would ordinarily allow the INSERT, UPDATE, DELETE or

superusers, roles with bypassrls, and target table owners should still

postgres_fdw: Add regression test for postgres_fdw.application_name GUC.
Commit
449ab63505 added postgres_fdw.application_name GUC that specifies
a value for application_name configuration parameter used when postgres_fdw
establishes a connection to a foreign server. Also commit
6e0cb3dec1
allowed it to include escape sequences. Both commits added the regression
tests for the GUC, but those tests were reverted by commits
98dbef90eb and
5e64ad3697 because they were unstable and caused some buildfarm members
to report the failure.
This is the third try to add the regression test for
postgres_fdw.application_name GUC.
One of issues to make the test unstable was to have used
postgres_fdw_disconnect_all() to close the existing remote connections.
The test expected that the remote connection and its corresponding backend
at the remote server disappeared just after postgres_fdw_disconnect_all()
was executed, but it could take a bit time for them to disappear.
To make sure that they exit, this commit makes the test use
pg_terminate_backend() with the timeout at the remote server, instead.
If the timeout is set to greater than zero, this function waits until
they are actually terminated (or until the given time has passed).
Another issue was that the test didn't take into consideration the case
where postgres_fdw.application_name containing some escape sequences was
converted to the string larger than NAMEDATALEN. In this case it was
truncated to less than NAMEDATALEN when it's passed to the remote server,
but the test expected wrongly that full string of application_name was
always viewable. This commit changes the test so that it can handle that case.

Create foreign key triggers in partitioned tables too

This also changes what tgisinternal means in some cases. Currently,
it means either that the trigger is an internal implementation object
of a foreign key constraint, or a "child" trigger on a partition
cloned from the trigger on the parent. This commit changes it to
only mean the former to avoid confusion. As for the latter, it can

Fix index-only scan plans when not all index columns can be returned.
If an index has both returnable and non-returnable columns, and one of
the non-returnable columns is an expression using a Var that is in a
returnable column, then a query returning that expression could result
in an index-only scan plan that attempts to read the non-returnable
column, instead of recomputing the expression from the returnable
column as intended.
To fix, redefine the "indextlist" list of an IndexOnlyScan plan node
as containing null Consts in place of any non-returnable columns.
This solves the problem by preventing setrefs.c from falsely matching
to such entries. The executor is happy since it only cares about the
exposed types of the entries, and ruleutils.c doesn't care because a
correct plan won't reference those entries. I considered some other
ways to prevent setrefs.c from doing the wrong thing, but this way
seems good since (a) it allows a very localized fix, (b) it makes
the indextlist structure more compact in many cases, and (c) the
indextlist is now a more faithful representation of what the index AM
will actually produce, viz. nulls for any non-returnable columns.

Remove dynamic translation of regression test scripts, step 1.
pg_regress has long had provisions for dynamically substituting path
names into regression test scripts and result files, but use of that
feature has always been a serious pain in the neck, mainly because
updating the result files requires tedious manual editing. Let's
get rid of that in favor of passing down the paths in environment
variables.
In addition to being easier to maintain, this way is capable of
dealing with path names that require escaping at runtime, for example
paths containing single-quote marks. (There are other stumbling
blocks in the way of actually building in a path that looks like
that, but removing this one seems like a good thing to do.) The key
coding rule that makes that possible is to concatenate pieces of a
dynamically-variable string using psql's \set command, and then use
the :'variable' notation to quote and escape the string for the next
level of interpretation.

Add fast path for validating UTF-8 text
Our previous validator used a traditional algorithm that performed
comparison and branching one byte at a time. It's useful in that
we always know exactly how many bytes we have validated, but that
precision comes at a cost. Input validation can show up prominently
in profiles of COPY FROM, and future improvements to COPY FROM such
as parallelism or faster line parsing will put more pressure on input
validation. Hence, add fast paths for both ASCII and multibyte UTF-8:
Use bitwise operations to check 16 bytes at a time for ASCII. If
that fails, use a "shift-based" DFA on those bytes to handle the
general case, including multibyte. These paths are relatively free
of branches and thus robust against all kinds of byte patterns. With
these algorithms, UTF-8 validation is several times faster, depending
on platform and the input byte distribution.
The previous coding in pg_utf8_verifystr() is retained for short
strings and for when the fast path returns an error.

Therefore, we could remove pg_strtouint64(), and use strtoull()

separate notation for parsing exactly 64-bit integers, matching the
type definition int64/uint64. For that, add new macros strtoi64() and
strtou64() in c.h as thin wrappers around strtol()/strtoul() or
strtoll()/stroull(). This makes these functions available everywhere

Always use ReleaseTupleDesc after lookup_rowtype_tupdesc et al.
The API spec for lookup_rowtype_tupdesc previously said you could use
either ReleaseTupleDesc or DecrTupleDescRefCount. However, the latter
choice means the caller must be certain that the returned tupdesc is
refcounted. I don't recall right now whether that was always true
when this spec was written, but it's certainly not always true since
we introduced shared record typcaches for parallel workers. That means
that callers using DecrTupleDescRefCount are dependent on typcache
behavior details that they probably shouldn't be. Hence, change the API
spec to say that you must call ReleaseTupleDesc, and fix the half-dozen
callers that weren't.
AFAICT this is just future-proofing, there's no live bug here.

Improve parallel vacuum implementation.
Previously, in parallel vacuum, we allocated shmem area of
IndexBulkDeleteResult only for indexes where parallel index vacuuming is
safe and had null-bitmap in shmem area to access them. This logic was too
complicated with a small benefit of saving only a few bits per indexes.
In this commit, we allocate a dedicated shmem area for the array of
LVParallelIndStats that includes a parallel-safety flag, the index vacuum
status, and IndexBulkdeleteResult. There is one array element for every
index, even those indexes where parallel index vacuuming is unsafe or not
worthwhile. This commit makes the code clear by removing all
bitmap-related code.
Also, add the check each index vacuum status after parallel index vacuum
to make sure that all indexes have been processed.

Adjust behavior of some env settings for the TAP tests of MSVC
edc2332 has introduced in vcregress.pl some control on the environment
variables LZ4, TAR and GZIP_PROGRAM to allow any TAP tests to be able
use those commands. This makes the settings more consistent with
src/Makefile.global.in, as the same default gets used for Make and MSVC
builds.
Each parameter can be changed in buildenv.pl, but as a default gets
assigned after loading buldenv.pl, it is not possible to unset any of
these, and using an empty value would not work with "||=" either. As
some environments may not have a compatible command in their PATH (tar
coming from MinGW is an issue, for one), this could break tests without
an exit path to bypass any failing test. This commit changes things so
as the default values for LZ4, TAR and GZIP_PROGRAM are assigned before
loading buildenv.pl, not after. This way, we keep the same amount of
compatibility as a GNU build with the same defaults, and it becomes
possible to unset any of those values.
While on it, this adds some documentation about those three variables in
the section dedicated to the TAP tests for MSVC.

Remove InitXLOGAccess().
It's not great that RecoveryInProgress() calls InitXLOGAccess(),
because a status inquiry function typically shouldn't have the side
effect of performing initializations. We could fix that by calling
InitXLOGAccess() from some other place, but instead, let's remove it
altogether.
One thing InitXLogAccess() did is initialize wal_segment_size, but it
doesn't need to do that. In the postmaster, PostmasterMain() calls
LocalProcessControlFile(), and all child processes will inherit that
value -- except in EXEC_BACKEND bulds, but then each backend runs
SubPostmasterMain() which also calls LocalProcessControlFile().
The other thing InitXLOGAccess() did is update RedoRecPtr and
doPageWrites, but that's not critical, because all code that uses
them will just retry if it turns out that they've changed. The
only difference is that most code will now see an initial value that
is definitely invalid instead of one that might have just been way
out of date, but that will only happen once per backend lifetime,
so it shouldn't be a big deal.

This change attracted an above-average amount of dissent, because
it means that a server with default settings will produce some amount
of log output even if nothing has gone wrong. However, by my count,
the mailing list discussion had about twice as many people in favor
of the change as opposed. The reasons for believing that the extra
log output is not an issue in practice are: (1) the rate at which
messages can be generated by this setting is bounded to one every
few minutes on a properly-configured system and (2) production
systems tend to have a lot more junk in the log from that due to
failed connection attempts, ERROR messages generated by application
activity, and the like.

Create a new type category for "internal use" types.
Historically we've put type "char" into the S (String) typcategory,
although calling it a string is a stretch considering it can only
store one byte. (In our actual usage, it's more like an enum.)
This choice now seems wrong in view of the special heuristics
that parse_func.c and parse_coerce.c have for TYPCATEGORY_STRING:
it's not a great idea for "char" to have those preferential casting
behaviors.
Worse than that, recent patches inventing special-purpose types
like pg_node_tree have assigned typcategory S to those types,
meaning they also get preferential casting treatment that's designed
on the assumption that they can hold arbitrary text.
To fix, invent a new category TYPCATEGORY_INTERNAL for internal-use
types, and assign that to all these types. I used code 'Z' for
lack of a better idea ('I' was already taken).
This change breaks one query in psql/describe.c, which now needs to
explicitly cast a catalog "char" column to text before concatenating
it with an undecorated literal. Also, a test case in contrib/citext
now needs an explicit cast to convert citext to "char". Since the
point of this change is to not have "char" be a surprisingly-available
cast target, these breakages seem OK.
