For regex escape sequences, just test directly for the relevant ASCII

classification.
This fixes an assertion failure when a locale considers a non-ASCII

The code variables referring to these fields are kept unchanged so as
they can keep their context about I/O.

We've long used "--strip-unneeded" for shared libraries but plain
"-x" for static libraries when stripping symbols with GNU strip.
There doesn't seem to be any really good reason for that though,
since --strip-unneeded produces smaller output (as "-x" alone
does not remove debug symbols). Moreover it seems that
llvm-strip, although it identifies as GNU strip, misbehaves when
given "-x" for this purpose. It's unclear whether that's
intentional or a bug in llvm-strip, but in any case it seems like
changing to use --strip-unneeded in all cases should be a win.
Note that this doesn't change our behavior when dealing with
non-GNU strip.
Per gripes from Ed Maste and Palle Girgensohn. Back-patch,
in case anyone wants to use llvm-strip with stable branches.

The "lev" name that appeared in NEWROOT nbtree record desc output was
inconsistent with the symbol name from the underlying C struct. It was
also inconsistent with nbtdesc output for other nearby record types with
similar level fields.
Standardize on "level" to make everything consistent.
Follow-up to commit 1c453cfd.
Recent enhancements to rmgr desc routines that made the output summarize
certain block data (added by commits 7d8219a4 and 1c453cfd) dealt with
records that lack relevant block data (and so have nothing to give a
more detailed summary of) by testing !DecodedBkpBlock.has_image. As a
result, more detailed descriptions of block data were not output when
wal_consistency_checking was enabled.
This bug affected records with summarizable block data that also
happened to have an FPI that the REDO routine isn't supposed to apply
(FPIs used for consistency checking purposes only). The presence of
such an FPI was incorrectly taken to indicate the absence of block data.
To fix, test DecodedBkpBlock.has_data, not !DecodedBkpBlock.has_image.
This is the exact condition that we care about, not an inexact proxy.

The error message for a missing or invalid system CA when using
sslrootcert=system differs based on the OpenSSL version used.
In OpenSSL 1.0.1-3.0 it is reported as SSL Error, with varying
degrees of helpfulness in the error message. With OpenSSL 3.1 it
is reported as an SSL SYSCALL error with "Undefined error" as
the error message. This fix pulls out the particular error in
OpenSSL 3.1 as a certificate verify error in order to help the
user better figure out what happened, and to keep the ssl test
working. While there is no evidence that extracing the errors
will clobber errno, this adds a guard against that regardless
to also make the consistent with how we handle OpenSSL errors
elsewhere. It also memorizes the output from OpenSSL 3.0 in
the test in cases where the system CA isn't responding.

Perl and child programs. That breaks commit cd82e5c79's attempt

Commit c6f2f01611 purported to make
this work, but problems remained. In a plain-format backup, the
files from an in-place tablespace got included in the tar file for
the main tablespace, which is wrong but it's not clear that it
has any user-visible consequences. In a tar-format backup, the
TABLESPACE_MAP option is used, and so we never iterated over
pg_tblspc and thus never backed up the in-place tablespaces
anywhere at all.
To fix this, reverse the changes in that commit, so that when we scan
pg_tblspc during a backup, we create tablespaceinfo objects even for
in-place tablespaces. We set the field that would normally contain the
absolute pathname to the relative path pg_tblspc/${TSOID}, and that's
good enough to make basebackup.c happy without any further changes.
However, pg_basebackup needs a couple of adjustments to make it work.
First, it needs to understand that a relative path for a tablespace
means it's an in-place tablespace. Second, it needs to tolerate the
situation where restoring the main tablespace tries to create
pg_tblspc or a subdirectory and finds that it already exists, because
we restore user-defined tablespaces before the main tablespace.
Since in-place tablespaces are only intended for use in development
and testing, no back-patch.

When compiled with -C ORACLE, ecpg_get_data() had a one-off issue where
it would incorrectly store the null terminator byte to str[-1] when
varcharsize is 0, which is something that can happen when using SQLDA.
This would eat 1 byte from the previous field stored, corrupting the
results generated.
All the callers of ecpg_get_data() estimate and allocate enough storage
for the data received, and the fix of this commit relies on this
assumption. Note that this maps to the case where no padding or
truncation is required.
This issue has been introduced by 3b7ab43 with the Oracle compatibility

If the last few pages in the specified range are empty (all zero),
then log_newpage_range() could try to emit an empty WAL record
containing no FPIs. This at least upsets an Assert in
ReserveXLogInsertLocation, and might perhaps have bad real-world
consequences in non-assert builds.
This has been broken since log_newpage_range() was introduced,
but the case was hard if not impossible to hit before commit 3d6a98457
decided it was okay to leave VM and FSM pages intentionally zero.
Nonetheless, it seems prudent to back-patch. log_newpage_range()
was added in v12 but later back-patched, so this affects all
supported branches.

The nbtree VACUUM WAL record stores its page offset number payload in
blk 0 (just like the closely related nbtree DELETE WAL record). Commit
ebd551f5 fixed a similar issue with the DELETE WAL record, but missed
this one.
We have two existing conventions for long options: either alphabetical
among short options, or all long options after all the short options.
But the convention apparently used here, next to a functionally
related option, is not one of them.
Here we remove the notes which mention which version the given vacuumdb
option is available from. There are now 11 of these notes and they're
both quite untidy and take up far more space than they seem to be worth.
On running a print preview of the compiled HTML, removing these notes
saves about 1 A4 page (~20% less space).
If people need to see which options are available on older versions, then
consulting the documents for that version seems like a good idea. In any
case, when using newer vacuumdb versions on older servers, the user will
receive an error if they try to use an unsupported option.
Additionally, 3 of the notes are warning about the option only being
available from PostgreSQL 9.6 and later. That version's support ended 2.5
years ago. So, it's quite clear that the value of these notes diminishes
over time.

Other vacuumdb options seem to have notes about which version they're
available from, so let's follow this trend for the newly added
--buffer-usage-limit option.
This addresses various deficiencies in the documentation for VACUUM and
ANALYZE's BUFFER_USEAGE_LIMIT docs.
Here we declare "size" in the syntax synopsis for VACUUM and ANALYZE's
BUFFER_USAGE_LIMIT option and then define exactly what values can be
specified for it in the section for that below.
Also, fix the incorrect ordering of vacuumdb options both in the documents
and in vacuumdb's --help output. These should be in alphabetical order.
In passing also add the minimum/maximum range for the BUFFER_USAGE_LIMIT
option. These will also serve as example values that can be modified and

Buildfarm member hamerkop is unhappy that daitch_mokotoff.c "contains
a character that cannot be represented in the current code page
(932). Save the file in Unicode format to prevent data loss". There
are a lot of non-ASCII characters in comments, but I do not see any
outside a comment, so this is just cosmetic. Nonetheless the warning
is fairly scary and people might waste time trying to understand the
cause, so we ought to silence it.
We have only one other occurrence of a non-ASCII character in .c or .h
files in the tree: predicate.c mentions "Uwe Röhm". It's far from
clear why hamerkop isn't complaining about that too; but it isn't,
so maybe there is some special provision for accented Roman letters.
We can remove the non-letter symbols from the comment for
iso8859_1_to_ascii_upper without any real loss of usefulness,
so let's try that first to see if it silences the warning.

For some reason I had not implemented RBM_ZERO_AND_CLEANUP_LOCK support in
ExtendBufferedRelTo(), likely thinking it not being reachable. But it is
reachable, e.g. when replaying a WAL record for a page in a relation that
subsequently is truncated (likely only reachable when doing crash recovery or
PITR, not during ongoing streaming replication).
As now all of the RBM_* modes are supported, remove assertions checking mode.
As we had no test coverage for this scenario, add a new TAP test. There's
plenty more that ought to be tested in this area...
