recovery.  In the first place, it doesn't work because slru's
latest_page_number isn't set up yet (this is why we've been hearing reports
of strange "apparent wraparound" log messages during crash recovery, but
only from people who'd managed to advance their next-mxact counters some
considerable distance from 0).  In the second place, it seems a bit unwise
to be throwing away data during crash recovery anwyway.  This latter
consideration convinces me to just disable truncation during recovery,
rather than computing latest_page_number and pushing ahead.

  - Few README fixes
  - Keep imath Id string, put $PostgreSQL$ separately.

Patch from Marko Kreen.

just exec instead of creating a subprocess.  This reduces process usage
from four processes per parallel test to two.  I have no idea whether
a comparable optimization is possible or useful in the Windows port.

'make install' or 'initdb' fails.  Also minor simplification of fgets()
usage --- fgets guarantees a trailing null anyway.

enthusiastic copy and paste ...

This allows it to be used on Windows without installing mingw
(though you do still need 'diff'), and opens the door to future
improvements such as message localization.

"DESCRIPTION", which is actually only allowed for device drivers. The
compilers ignore it with a warning - if we remove them, we get rid of
the warning.

code to forcibly drop regressuser[1-4] and regressgroup[1-2].  Instead,
let the privileges.sql test do that for itself (this is made easy by
the recent addition of DROP ROLE IF EXISTS).  Per a recent patch proposed
by Joachim Wieland --- the rest of his patch is superseded by the
rewrite into C, but this is a good idea we should adopt.

pg_usleep at all.  Instead call the replacement function in
port/win32/signal.c by that name.  Avoids tricky macro-redefinition
logic and suppresses a compiler warning; furthermore it ensures that
no one can accidentally use the non-signal-aware version of pg_usleep
in a Windows backend.

EINTR; the stats code was failing to do this and so were a couple of places
in the postmaster.  The stats code assumed that recv() could not return EINTR
if a preceding select() showed the socket to be read-ready, but this is
demonstrably false with our Windows implementation of recv(), and it may
not be the case on all Unix variants either.  I think this explains the
intermittent stats regression test failures we've been seeing, as well
as reports of stats collector instability under high load on Windows.

Backpatch as far as 8.0.

I think this explains the 'implicit declaration of function gai_strerror'
warnings visible in the current buildfarm report from snake: if
sys/socket.h is included again after getaddrinfo.h, the file would
merrily undefine the gai_strerror macro.

This doesn't really matter for ordinary building of Postgres, but it's
useful for automated checks, such as my just-committed pgcheckdefines.

compiler warning, specifically #ifdef or #if defined tests on symbols
that are defined in a file not included.  The results are a bit noisy
and require care to interpret, but it's a lot better than no tool at all.

I'm going to insist on reversion of this entire patch unless pgrminclude
is upgraded to a less broken state, but in the meantime let's get contrib
passing regression again.
