This commit bumps the runtime value of _WIN32_WINNT to be 0x0A00 for any
builds on Windows. Hence, this makes Windows 10 the minimal requirement
when running PostgreSQL under WIN32, be it for builds of Cygwin, MinGW
or Visual Studio.
The previous minimal runtime version was either Windows Vista when
building with at least Visual Studio 2015 or Windows XP for the rest.
Windows 10 is the most modern version supported by Microsoft, and per
discussion, as we don't have buildfarm members that run older versions
anymore, this is the minimal supported version that suits better for our
needs. This will actually make easier the development of some patches,
two being async I/O and large page handling by avoiding a lot of
compatibility gotchas, on platforms that have most likely few users
anyway.
It is possible to remove MIN_WINNT in win32.h and the macros
IsWindowsXXXOrGreater() that were used in the code at runtime to check
which version of Windows was getting used. The change in pg_locale.c
comes from Juan. Note that all my tests passed, and that the CI is
green. The buildfarm will quickly tell if this needs more adjustments.

We have been using the term RelFileNode to refer to either (1) the
integer that is used to name the sequence of files for a certain relation
within the directory set aside for that tablespace/database combination;
or (2) that value plus the OIDs of the tablespace and database; or
occasionally (3) the whole series of files created for a relation
based on those values. Using the same name for more than one thing is
confusing.
Replace RelFileNode with RelFileNumber when we're talking about just the
single number, i.e. (1) from above, and with RelFileLocator when we're
talking about all the things that are needed to locate a relation's files
on disk, i.e. (2) from above. In the places where we refer to (3) as
a relfilenode, instead refer to "relation storage".
Since there is a ton of SQL code in the world that knows about
pg_class.relfilenode, don't change the name of that column, or of other
SQL-facing things that derive their name from it.
On the other hand, do adjust closely-related internal terminology. For
example, the structure member names dbNode and spcNode appear to be
derived from the fact that the structure itself was called RelFileNode,
so change those to dbOid and spcOid. Likewise, various variables with
names like rnode and relnode get renamed appropriately, according to
how they're being used in context.
Hopefully, this is clearer than before. It is also preparation for
future patches that intend to widen the relfilenumber fields from its
current width of 32 bits. Variables that store a relfilenumber are now
declared as type RelFileNumber rather than type Oid; right now, these
are the same, but that can now more easily be changed.

Backpatch: 15-
When we changed some built-in functions to use anycompatiblearray
instead of anyarray, we created a dump/restore hazard for user-defined
operators and aggregates relying on those functions: the user objects
have to be modified to change their signatures similarly. This causes
pg_upgrade to fail partway through if the source installation contains
such objects. We generally try to have pg_upgrade detect such hazards
and fail before it does anything exciting, so add logic to detect
this case too.

Several buildfarm members are failing the pg_upgrade test in
REL_15_STABLE, though the identical test is fine in HEAD.
On thorntail it's possible to see that the problem is an
overlength socket path name, and I bet the same is true
on the others.
The normally-started postmasters used in the test are already
set up with short socket directory paths, but we neglected to
tell pg_upgrade itself to do likewise when starting child
postmasters, and indeed it seems to be explicitly selecting
the test directory instead.
Back-patch to v15 where the current test script was introduced.
(The previous script might have the same issue, because I don't
see any use of -s/--socketdir in it either; but we've had no

After commit 662dbe2c8, psql tab completion didn't conveniently
support the case of "ALTER EXTENSION foo UPDATE". It'd always
add "TO", which is fine if you want to specify a target version
but not if you don't ... and surely the latter is the much more
common case.
To fix, remove "TO" from the initially offered completion; you now
need to press TAB one additional time to get that. We won't try to
duplicate the old behavior of attempting initial completion on the
target version along with TO. It's too squirrelly to get the quoting
right, and this is such an infrequent usage that it doesn't seem worth
expending a lot of effort and special code on.

POSIX shm_open() can sleep for a long time and fail spuriously because
of contention on an internal lock file on Solaris (and presumably
illumos). Commit 389869af fixed the main problem with this, namely that
we could crash, but it's now clear that "posix" is not a good default.
Therefore, choose "sysv" at initdb time on Solaris and illumos. Other
choices are still available by editing the postgresql.conf file.

Second thoughts about 9cd43f6cb: given that we're staying bug-compatible
with the old behavior of using double not single quotes for extension
versions, we can simplify this completion code by pretending that
extension versions *are* identifiers, and not using VERBATIM. Then
_complete_from_query() will think that the query results are identifiers
in need of quoting, and we end up with the same behavior as before.
This doesn't work for Query_for_list_of_available_extension_versions_with_TO,
but let's just drop that: there is no other place where we handle
multi-keyword phrases that way, and it doesn't seem very desirable here
either. Handle completion of "UPDATE TO" in our more usual pattern.

In 02b8048ba I (tgl) got rid of the need for most tab-completion queries
to return pre-quoted identifiers. But I over-hastily removed the
quote_ident call from Query_for_list_of_available_extension_versions*
too; those still need it, because what is returned isn't an identifier
at all and will (almost?) always need quoting.
Arguably we should use quote_literal here instead. But quote_ident
works too and people may be used to that behavior, so stick with it.
In passing, fix inconsistent omission of schema-qualification in
Query_for_list_of_encodings. That's not a security issue per our
current guidelines, but it ought to be like the rest.

This reverts the changes to pg_upgrade's Makefile and .gitignore done in
15b6d21. The TAP tests run in isolation, executing pg_upgrade in
tmp_check/ in the build directory so as any files created in the
execution path (reindex_hash.sql and delete_old_cluster.{sh,bat}) are
never in the tree, so entries are not necessary in this case. However,
not having these impacts the cleanliness of the code tree when running
./pg_upgrade directly from src/bin/pg_upgrade/.
This commit adds back to .gitignore all the files generated in the
execution path, and the Makefile rule to clean them up if they exist.

This commit, in completion of 157f873, forces a ROLLBACK for
--single-transaction only when ON_ERROR_STOP is used when one of the
steps defined by -f/-c fails. Hence, COMMIT is always used when
ON_ERROR_STOP is not set, ignoring the status code of the last action
taken in the set of switches specified by -c/-f (previously ROLLBACK
would have been issued even without ON_ERROR_STOP if the last step
failed, while COMMIT was issued if a step in-between failed as long as
the last step succeeded, leading to more inconsistency).
While on it, this adds much more test coverage in this area when not
using ON_ERROR_STOP with multiple switch patterns involving -c and -f
for query files, single queries and slash commands.
The behavior of ON_ERROR_STOP is arguably a bug, but there was no much
support for a backpatch to force a ROLLBACK on a step failure, so this
change is done only on HEAD for now.

The new show-all-results feature in psql (7844c9918) went out of its
way to show notices next to the results of the statements (in a
multi-statement string) that caused them. This also had the
consequence that notices for a single statement were not shown until
after the statement had executed, instead of right away. After some
discussion, it seems very difficult to satisfy both of these goals, so
here we are giving up on the first goal and just show the notices as
we get them. This restores the pre-7844c9918 behavior for notices.

Some locales use a comma as decimal separator (like Czech or French),

38bfae3 has moved the contents written to files by pg_upgrade under a
new directory called pg_upgrade_output.d/ located in the new cluster's
data folder, and it used a simple structure made of two subdirectories
leading to a fixed structure: log/ and dump/. This design has made
weaker pg_upgrade on repeated calls, as we could get failures when
creating one or more of those directories, while potentially losing the
logs of a previous run (logs are retained automatically on failure, and
cleaned up on success unless --retain is specified). So a user would
need to clean up pg_upgrade_output.d/ as an extra step for any repeated
calls of pg_upgrade. The most common scenario here is --check followed
by the actual upgrade, but one could see a failure when specifying an
incorrect input argument value. Removing entirely the logs would have
the disadvantage of removing all the past information, even if --retain
was specified at some past step.
This result is annoying for a lot of users and automated upgrade flows.
So, rather than requiring a manual removal of pg_upgrade_output.d/, this
redesigns the set of output directories in a more dynamic way, based on
a suggestion from Tom Lane and Daniel Gustafsson. pg_upgrade_output.d/
is still the base path, but a second directory level is added, mostly
named after an ISO-8601-formatted timestamp (in short human-readable,
with milliseconds appended to the name to avoid any conflicts). The
logs and dumps are saved within the same subdirectories as previously,
as of log/ and dump/, but these are located inside the subdirectory
named after the timestamp.
The logs of a given run are removed only after a successful run if
--retain is not used, and pg_upgrade_output.d/ is kept if there are any
logs from a previous run. Note that previously, pg_upgrade would have
kept the logs even after a successful --check but that was inconsistent
compared to the case without --check when using --retain. The code in
charge of the removal of the output directories is now refactored into a
single routine.
Two TAP tests are added with some --check commands (one failure case and
one success case), to look after the issue fixed here. Note that the
tests had to be tweaked a bit to fit with the new directory structure so
as it can find any logs generated on failure. This is still going to
require a change in the buildfarm client for the case where pg_upgrade
is tested without the TAP test, though, but I'll tackle that with a
separate patch where needed.

psql --single-transaction is able to handle multiple -c and -f switches
in a single transaction since d5563d7d, but this had the surprising
behavior of forcing a transaction COMMIT even if psql failed with an
error in the client (for example incorrect path given to \copy), which
would generate an error, but still commit any changes that were already
applied in the backend. This commit makes the behavior more consistent,
by enforcing a transaction ROLLBACK if any commands fail, both
client-side and backend-side, so as no changes are applied if one error
happens in any of them.
Some tests are added on HEAD to provide some coverage about all that.
Backend-side errors are unreliable as IPC::Run can complain on SIGPIPE
if psql quits before reading a query result, but that should work
properly in the case where any errors come from psql itself, which is
what the original report is about.

The hard-wired PageOutput arguments in usage() and sibling functions
have been a perennial maintenance gotcha, and there's no reason to
think we'll ever get any better about that. Let's get rid of those
magic constants by constructing the output in a buffer where we can
count the newlines before calling PageOutput. (Perhaps this is
microscopically slower; but none of these functions are performance
critical, and anyway we might well be buying back all the cost by
avoiding having to pass most of the data through snprintf.c. I could
not detect any speed difference in a desultory check.) This also
gets rid of the need to assume that platform-specific variations in
the output are insignificant.
While at it, make the code shorter and more abstract by inventing
helper macros HELP0() and HELPN() to encapsulate the specific
output actions being invoked.

TAP tests are run from their own directory in the source tree, and in a
VPATH build the execution of the pg_upgrade command was leaving behind a
file in the source tree, that should be left untouched. In order to
avoid this issue, the test moves to PostgreSQL::Test::Utils::tmp_check,
so as any files generated by pg_upgrade do not impact the source tree,
but the build tree. This has as nice side-effect to make unnessary the
presence of such files in pg_upgrade's .gitignore and Makefile. This
strategy is similar to psql's test 010_tab_completion.pl, though the
reasons behind this choice are different.

- Switch from run_log() to command_ok(), as all the commands executed in

built for the execution the pg_regress command is reformatted, while on

refactor and consolidate that in the future, perhaps).
- Re-add the test for database names stressing the behavior of
backslashes with double quotes, mostly here for Windows.
