Since HAVE_UNIX_SOCKETS is now defined unconditionally, remove the macro
and drop a small amount of dead code.
The last known systems not to have them (as far as I know at least) were
QNX, which we de-supported years ago, and Windows, which now has them.
If a new OS ever shows up with the POSIX sockets API but without working
AF_UNIX, it'll presumably still be able to compile the code, and fail at
runtime with an unsupported address family error. We might want to
consider adding a HINT that you should turn off the option to use it if
your network stack doesn't support it at that point, but it doesn't seem
worth making the relevant code conditional at compile time.
Also adjust a couple of places in the docs and comments that referred to
builds without Unix-domain sockets, since there aren't any. Windows
still gets a special mention in those places, though, because we don't
try to use them by default there yet.

96ef3b8ff1 accidentally copied a not
applicable comment from the float8_pass_by_value code to the
data_checksums code. Remove that.
87d3b35a1c changed pg_upgrade to
checking the checksum version rather than just the Boolean presence of
checksums, but didn't change the field type in its ControlData struct
from bool. So this would not work correctly if there ever is a
checksum version larger than 1.
Now that lstat() reports junction points with S_IFLNK/S_ISLINK(), and
unlink() can unlink them, there is no need for conditional code for
Windows in a few places. That was expressed by testing for WIN32 or
S_ISLNK, which we can now constant-fold.
The coding around pgwin32_is_junction() was a bit suspect anyway, as we
never checked for errors, and we also know that errors can be spuriously
reported because of transient sharing violations on this OS. The
lstat()-based code has handling for that.
This also reverts 4fc6b6ee on master only. That was done because
lstat() didn't previously work for symlinks (junction points), but now
it does.

Commit 9a974cbcba arranged to preserve
the relfilenode of user tables across pg_upgrade, but failed to notice
that pg_upgrade treats pg_largeobject as a user table and thus it needs
the same treatment. Otherwise, large objects will appear to vanish
after a pg_upgrade.
Commit d498e052b4 fixed this problem
by teaching pg_dump to UPDATE pg_class.relfilenode for pg_largeobject
and its index. However, because an UPDATE on the catalog rows doesn't
change anything on disk, this can leave stray files behind in the new
cluster. They will normally be empty, but it's a little bit untidy.
Hence, this commit arranges to do the same thing using DDL. Specifically,
it makes TRUNCATE work for the pg_largeobject catalog when in
binary-upgrade mode, and it then uses that command in binary-upgrade
dumps as a way of setting pg_class.relfilenode for pg_largeobject and
its index. That way, the old files are removed from the new cluster.

This addresses a couple of bugs in the REINDEX grammar, introduced by
83011ce:
- A name was never specified for DATABASE/SYSTEM, even if the query
included one. This caused such REINDEX queries to always work with any
object name, but we should complain if the object name specified does
not match the name of the database we are connected to. A test is added
for this case in the main regression test suite, provided by Álvaro.
- REINDEX SYSTEM CONCURRENTLY [name] was getting rejected in the
parser. Concurrent rebuilds are not supported for catalogs but the
error provided at execution time is more helpful for the user, and
allowing this flavor results in a simplification of the parsing logic.
- REINDEX DATABASE CONCURRENTLY was rebuilding the index in a
non-concurrent way, as the option was not being appended correctly in
the list of DefElems in ReindexStmt (REINDEX (CONCURRENTLY) DATABASE was
working fine. A test is added in the TAP tests of reindexdb for this
case, where we already have a REINDEX DATABASE CONCURRENTLY query
running on a small-ish instance. This relies on the work done in
2cbc3c1 for SYSTEM, but here we check if the OIDs of the index relations
match or not after the concurrent rebuild. Note that in order to get
this part to work, I had to tweak the tests so as the index OID and
names are saved separately. This change not affect the reliability or
of the coverage of the existing tests.
While on it, I have implemented a tweak in the grammar to reduce the
parsing by one branch, simplifying things even more.

This patch adds a new SUBSCRIPTION parameter "origin". It specifies
whether the subscription will request the publisher to only send changes
that don't have an origin or send changes regardless of origin. Setting it
to "none" means that the subscription will request the publisher to only
send changes that have no origin associated. Setting it to "any" means
that the publisher sends changes regardless of their origin. The default
is "any".
Usage:
CREATE SUBSCRIPTION sub1 CONNECTION 'dbname=postgres port=9999'
PUBLICATION pub1 WITH (origin = none);
This can be used to avoid loops (infinite replication of the same data)
among replication nodes.
This feature allows filtering only the replication data originating from
WAL but for initial sync (initial copy of table data) we don't have such a
facility as we can only distinguish the data based on origin from WAL. As
a follow-up patch, we are planning to forbid the initial sync if the
origin is specified as none and we notice that the publication tables were
also replicated from other publishers to avoid duplicate data or loops.
We forbid to allow creating origin with names 'none' and 'any' to avoid
confusion with the same name options.

Per discussion, this commit includes a couple of changes to these two
flavors of REINDEX:
* The grammar is changed to make the name of the object optional, hence
one can rebuild all the indexes of the wanted area by specifying only
"REINDEX DATABASE;" or "REINDEX SYSTEM;". Previously, the object name
was mandatory and had to match the name of the database on which the
command is issued.
* REINDEX DATABASE is changed to ignore catalogs, making this task only
possible with REINDEX SYSTEM. This is a historical change, but there
was no way to work only on the indexes of a database without touching
the catalogs. We have discussed more approaches here, like the addition
of an option to skip the catalogs without changing the original
behavior, but concluded that what we have here is for the best.
This builds on top of the TAP tests introduced in 5fb5b6c, showing the
change in behavior for REINDEX SYSTEM. reindexdb is updated so as we do
not issue an extra REINDEX SYSTEM when working on a database in the
non-concurrent case, something that was confusing when --concurrently
got introduced, so this simplifies the code.

Adding such commands in the main regression test suite is not a good
approach performance-wise as it impacts all the objects in the
regression database, so this additional coverage is added in the TAP
tests of reindexdb where we already run a few REINDEX commands with
SYSTEM and DATABASE so there is no runtime difference for the test.
This additional coverage checks which relations are rewritten with
relfilenode changes, as of:
- a toast index in user table.
- a toast index in catalog table.
- a catalog index.
- a user index.
This test suite is something I have implemented for a separate patch
that reworks a bit the way we handle these two REINDEX behaviors, but it
has enough value in itself to be in a separate commit. This also makes
easier to follow what actually changes once the REINDEX logic is
reworked (currently, DABATASE rewrites both catalog and user tables, and
SYSTEM works only on catalogs).

pg_upgrade does not use common/logging.c, which is unfortunate
but changing it to do so seems like more work than is justified.
However, we really need to make it work more like common/logging.c
in one respect: the latter expects supplied message strings to not
end with a newline, instead adding one internally. As it stands,
pg_upgrade's logging facilities expect a caller-supplied newline
in some cases and not others, which is already an invitation to bugs,
but the inconsistency with our other frontend code makes it worse.
There are already several places with missing or extra newlines,
and it's inevitable that there won't be more if we let this stand.
Hence, run around and get rid of all trailing newlines in message
strings, and add an Assert that there's not one, similar to the
existing Assert in common/logging.c. Adjust the logging functions
to supply a newline at the right places.
(Some of these strings also have a *leading* newline, which would
be a good thing to get rid of too; but this patch doesn't attempt
that.)
There are some consequent minor changes in output. The ones that
aren't outright bug fixes are generally removal of extra blank
lines that the original coding intentionally inserted. It didn't

Commit 9a974cbcba did this for user

table will apparently be empty on the new cluster, while all of your
objects will end up with an orphaned file.
With this fix, instead of the old cluster's pg_largeobject files ending
up orphaned, the original files fro the new cluster do. That's mostly
harmless because we expect the table to be empty, but we might want

This commit bumps the runtime value of _WIN32_WINNT to be 0x0A00 for any

The previous minimal runtime version was either Windows Vista when

Windows 10 is the most modern version supported by Microsoft, and per

anymore, this is the minimal supported version that suits better for our

two being async I/O and large page handling by avoiding a lot of
