for indexes on system columns.  Per complaint from Peter.

environment strings need to be moved around, do so when called from
initial startup (main.c), not in init_ps_status.  This eliminates the
former risk of invalidating saved environment-string pointers, since
no code has yet had a chance to grab any such pointers when main.c
is running.

cleanups too.

per suggestion from Peter.  Simplify several APIs by transmitting the
original argv location directly from main.c to ps_status.c, instead of
passing it down through several levels of subroutines.

out glibc doesn't actually export this variable, so we need a different
solution.

Mask both typmod subfields for INTERVAL to avoid setting the high bit,
 per dire warning from Tom Lane.
Clear tmask for DTK_ISO_TIME case to avoid time zone troubles.
 Symptom reported by Tom Lane.
Clean up checking for valid time zone info in output routine.
 This should now work for both SQL99 and Unix-style time zones.
Put in explicit check for INTERVAL() typmod rounding to avoid accumulating
 cruft in the lower bits. Not sure that this helps, but we'll need to do
 something. The symptom is visible with a query like
 select interval(2) '10000 days 01:02:03.040506';
Regression tests are patched to repair the Tom Lane symptom, and all pass.

just after receipt of the startup packet.  Now, postmaster children

'postgres: user database host authentication'.  Also, do an
init_ps_display for startup/shutdown/checkpoint subprocesses,

attempting to start a checkpoint process before any connections have
been received led to calling PostmasterRandom before setting random_seed.

authentication failed' and a 'send() failed: Broken pipe' message
on every connection from psql in password auth mode.  Problem is
that psql doesn't ask user for a password until it sees a password
challenge failure, and libpq just closes the connection unceremoniously
if it's challenged for a password when it hasn't got one to send.
Accordingly, EOF from the client after asking for a password is
normal behavior and should not result in postmaster log entries.
