While monitoring the code, a couple of issues related to string
translation has showed up:
- Some routines for auto-updatable views return an error string, which
sometimes missed the shot. A comment regarding string translation is
added for each routine to help with future features.
- GSSAPI authentication missed two translations.
- vacuumdb handles non-translated strings.

The regexes used in 102_vacuumdb_stages.pl to check the postmaster log
for expected output contained several places with ".*.*", which is
underdetermined and can cause exponential runtime growth in Perl's regex
matcher (since it's not bright enough not to waste time seeing whether
different splits of the same substring would allow a match). We were
fortunate that the amount of text in the postmaster log was generally not
enough to make the runtime go to the moon; although commit 6271fceb8 had
been on the hairy edge of an obvious problem, thanks to its increasing the
default log verbosity to DEBUG1. Experimentation shows that anyone who
tried to run this test case with an even higher log verbosity would have
been in for serious pain. But even at default logging level, fixing this
saves several hundred ms on my workstation, more on slower buildfarm
members.
Remove the extra ".*"s, restoring more-or-less-linear matching speed.
Back-patch to 9.4 where the test case was added, mostly in case anyone
tries to do related debugging in a back branch.

Avoid storing the result of PQsocket() in a pgsocket variable; it's
declared as int, and the no-socket test is properly written as "x < 0"
not "x == PGINVALID_SOCKET". This accidentally had no bad effect
because we never got to init_slot() with a bad connection, but it's
still wrong.
Actually, it seems like we should avoid storing the result for a long
period at all. The function's not so expensive that it's worth avoiding,
and the existing coding technique here would fail if anyone tried to
PQreset the connection during the life of the program. Hence, just
re-call PQsocket every time we construct a select(2) mask.
Speaking of select(), GetIdleSlot imagined that it could compute the
select mask once and continue to use it over multiple calls to
select_loop(), which is pretty bogus since that would stomp on the
mask on return. This could only matter if the function's outer loop
iterated more than once, which is unlikely (it'd take some connection
receiving data, but not enough to complete its command). But if it
did happen, we'd acquire "tunnel vision" and stop watching the other
connections for query termination, with the effect of losing parallelism.
Another way in which GetIdleSlot could lose parallelism is that once
PQisBusy returns false, it would lock in on that connection and do
PQgetResult until that returns NULL; in some cases that could result
in blocking. (Perhaps this can never happen in vacuumdb due to the
limited set of commands that it can issue, but I'm not quite sure
of that, and even if true today it's not a future-proof assumption.)
Refactor the code to do that properly, so that it risks blocking in
PQgetResult only in cases where we need to wait anyway.
Another loss-of-parallelism problem, which *is* easily demonstrable,
is that any setup queries issued during prepare_vacuum_command() were
always issued on the last-to-be-created connection, whether or not
that was idle. Long-running operations on that connection thus
prevented issuance of additional operations on the other ones, except
in the limited cases where no preparatory query was needed. Instead,
wait till we've identified a free connection and use that one.
Also, avoid core dump due to undersized malloc request in the case
that no tables are identified to be vacuumed.
The bogus no-socket test was noted by CharSyam, the other problems
identified in my own code review. Back-patch to 9.5 where parallel
vacuumdb was introduced.

The Makefile portion of 91f3ffc5249eff99c311fb27e7b29a44d9c62be1 broke
the MSVC build. This patch reverts the changes to the Makefile and
adjusts it to work with the new code, while keeping the actual code
changes from the original patch.

This makes the client programs behave as documented regardless of the
connect-time search_path and regardless of user-created objects. Today,
a malicious user with CREATE permission on a search_path schema can take
control of certain of these clients' queries and invoke arbitrary SQL
functions under the client identity, often a superuser. This is
exploitable in the default configuration, where all users have CREATE
privilege on schema "public".
This changes behavior of user-defined code stored in the database, like
pg_index.indexprs and pg_extension_config_dump(). If they reach code
bearing unqualified names, "does not exist" or "no schema has been
selected to create in" errors might appear. Users may fix such errors
by schema-qualifying affected names. After upgrading, consider watching
server logs for these errors.
The --table arguments of src/bin/scripts clients have been lax; for
example, "vacuumdb -Zt pg_am\;CHECKPOINT" performed a checkpoint. That
now fails, but for now, "vacuumdb -Zt 'pg_am(amname);CHECKPOINT'" still
performs a checkpoint.
Back-patch to 9.3 (all supported versions).

Buildfarm members skink and sungazer have both recently failed this
test, with symptoms indicating that the default 3-second timeout
isn't quite enough for those very slow systems. There's no reason
to be miserly with this timeout, so boost it to 60 seconds.
Back-patch to all versions containing this test. That may be overkill,
because the failure has only been observed in the v10 branch, but
I don't feel like having to revisit this later.

<sys/select.h> is required by POSIX.1-2001 to get the prototype of
select(2), but nearly no systems enforce that because older standards
let you get away with including some other headers. Recent OpenBSD
hacking has removed that frail touch of friendliness, however, which
broke some compiles; fix all the way back to 9.1 by adding the required
standard. Only vacuumdb.c was reported to fail, but it seems easier to
fix the whole lot in a fell swoop.

Due to simplistic quoting and confusion of database names with conninfo
strings, roles with the CREATEDB or CREATEROLE option could escalate to
superuser privileges when a superuser next ran certain maintenance
commands. The new coding rule for PQconnectdbParams() calls, documented
at conninfo_array_parse(), is to pass expand_dbname=true and wrap
literal database names in a trivial connection string. Escape
zero-length values in appendConnStrVal(). Back-patch to 9.1 (all
supported versions).

These programs nominally accepted conninfo strings, but they would
proceed to use the original dbname parameter as though it were an
unadorned database name. This caused "reindexdb dbname=foo" to issue an
SQL command that always failed, and other programs printed a conninfo
string in error messages that purported to print a database name. Fix
both problems by using PQdb() to retrieve actual database names.
Continue to print the full conninfo string when reporting a connection
failure. It is informative there, and if the database name is the sole
problem, the server-side error message will include the name. Beyond
those user-visible fixes, this allows a subsequent commit to synthesize
and use conninfo strings without that implementation detail leaking into
messages. As a side effect, the "vacuuming database" message now
appears after, not before, the connection attempt. Back-patch to 9.1
(all supported versions).

This reverts most of commit 83dec5a71 in favor of having connectDatabase()
store the possibly-reusable password in a static variable, similar to the
coding we've had for a long time in pg_dump's version of that function.
To avoid possible problems with unwanted password reuse, make callers
specify whether it's reasonable to attempt to re-use the password.
This is a wash for cases where re-use isn't needed, but it is far simpler
for callers that do want that. Functionally there should be no difference.
Even though we're past RC1, it seems like a good idea to back-patch this
into 9.5, like the prior commit. Otherwise, if there are any third-party
users of connectDatabase(), they'll have to deal with an API change in
9.5 and then another one in 9.6.

The formatting modes that depend on knowledge of the terminal window width
did not work right when printing a query result that's been fetched in
sections (as a result of FETCH_SIZE). ExecQueryUsingCursor() would force
use of the pager as soon as there's more than one result section, and then
print.c would see an output file pointer that's not stdout and incorrectly
conclude that the terminal window width isn't relevant.
This has been broken all along for non-expanded "wrapped" output format,
and as of 9.5 the issue affects expanded mode as well. The problem also
caused "\pset expanded auto" mode to invariably *not* switch to expanded
output in a segmented result, which seems to me to be exactly backwards.
To fix, we need to pass down an "is_pager" flag to inform the print.c
subroutines that some calling level has already replaced stdout with a
pager pipe, so they should (a) not do that again and (b) nonetheless honor
the window size. (Notably, this makes the first is_pager test in
print_aligned_text() not be dead code anymore.)
This patch is a bit invasive because there are so many existing calls of
printQuery()/printTable(), but fortunately all but a couple can just pass
"false" for the added parameter.
Back-patch to 9.5 but no further. Given the lack of field complaints,
it's not clear that we should change the behavior in stable branches.
Also, the API change for printQuery()/printTable() might possibly break
third-party code, again something we don't like to do in stable branches.
However, it's not quite too late to do this in 9.5, and with the larger
scope of the problem there, it seems worth doing.

Having the script prompt for passwords over and over was a preexisting
problem when it processed multiple databases or when it processed
multiple analyze stages, but the parallel mode introduced in commit
a179232047 made it worse.
Fix the annoyance by keeping a copy of the password used by the first
connection that requires one. Since users can (currently) only have a
single password, there's no need for more complex arrangements (such as
remembering one password per database).
Per bug #13741 reported by Eric Brown. Patch authored and

The "check" target no longer needs to depend on "all", because it now
runs "install" directly, which in turn depends on "all". Doing both
will cause problems with parallel make, because two builds will run next
to each other.
Also remove the redirection of the temp-install output into a log file.
This was appropriate when this was done from within pg_regress, but now
it's just a regular make run, and especially with the above changes this
will now take the place of running the "all" target before the test
suites.

Some of the TAP tests were supposing that PG programs would accept switches
after non-switch arguments on their command lines. While GNU getopt_long()
does allow that, our own implementation does not, and it's nowhere
suggested in our documentation that such cases should work. Adjust the
tests to use only the documented syntax.
Back-patch to 9.4, since without this the TAP tests fail when run with
src/port's getopt_long() implementation.
