83dc5908c2 pg_test_fsync: Update output format
Apparently, computers are now a bit faster than when this was first
added, so we need to make room for a digit or two in the ops/sec format.

While we're at it, adjust some of the other output for a more consistent
line length.

0ffc201a51 Add file version information to most installed Windows binaries.
Prominent binaries already had this metadata.  A handful of minor
binaries, such as pg_regress.exe, still lack it; efforts to eliminate
such exceptions are welcome.

0a78320057 pgindent run for 9.4
This includes removing tabs after periods in C comments, which was
applied to back branches, so this change should not effect backpatching.

43f6388931 pg_test_fsync: expand ops/sec display
Expand ops/sec by two digits to maintain alignment on servers with fast
I/O subsystems, e.g. can now display < 10M ops/sec with consistent
alignment.

b5ed21998c Fix pg_test_fsync, broken by xloginsert scaling patch.
I didn't realize that ALIGNOF_XLOG_BUFFER was used in pg_test_fsync.

06b804377c Remove undocumented -h (help) option
The -h option was not supported by many tools, and not documented, so
remove them for consistency from pg_upgrade, pg_test_fsync, and
pg_test_timing.

3c07fbf40b Use pqsignal() in contrib programs rather than calling signal(2) directly.
The semantics of signal(2) are more variable than one could wish; in
particular, on strict-POSIX platforms the signal handler will be reset
to SIG_DFL when the signal is delivered.  This demonstrably breaks
pg_test_fsync's use of SIGALRM.  The other changes I made are not
absolutely necessary today, because the called handlers all exit the
program anyway.  But it seems like a good general practice to use
pqsignal() exclusively in Postgres code, now that we have it available
everywhere.

70ec2f8f43 Improve the documentation about commit_delay.
Clarify the docs explaining what commit_delay does, and add a
recommendation about a useful value for it, namely half of the single-page
fsync time reported by pg_test_fsync.  This is informed by testing of
the new-in-9.3 implementation of commit_delay; in prior versions it
was far harder to arrive at a useful setting.

In passing, do some wordsmithing and markup-fixing in the same general
area.

Also, change pg_test_fsync's default time-per-test from 2 seconds to 5.
The old value was about the minimum at which the results could be taken
seriously at all, and so seems a tad optimistic as a default.

629b3af27d Convert contrib modules to use the extension facility.
This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK.  But it's time to get some
buildfarm cycles on it.

sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

37eb2cd4ad More pg_test_fsync fixups.
Reduce #includes to minimum actually needed; in particular include
postgres_fe.h not postgres.h, so as to stop build failures on some
platforms.

Use get_progname() instead of hardwired program name; improve error
checking for command line syntax; bring error messages into line with
style guidelines; include strerror result in die() cases.

Un-break Windows build (I hope) by making the HAVE_FSYNC_WRITETHROUGH
code match the backend.  Fix incorrect program help message.  static-ize
all functions.

bc616703e8 Clean up pg_test_fsync commit.
Actually rename the program, rather than just claiming we did.  Hook it
into the build system.  Get rid of useless dependency on libpq.  Clean up
#include list and messy whitespace.
