> * Have standalone backend read postgresql.conf

(usually bison output files), not as standalone files.  This hack
works around flex's insistence on including <stdio.h> before we are
able to include postgres.h; postgres.h will already be read before
the compiler starts to read the flex output file.  Needed for largefile
support on some platforms.

from WARNING to NOTICE, since they are expected messages in common cases.

core file to be produced for debugging, and avoids trying to run the
normal proc-exit cleanup hooks, which are likely to cause additional
problems if the system is hosed.

this returns NULL, which confuses the code.

between signal handler and enable/disable code, avoid accumulation of
timing error due to trying to maintain remaining-time instead of
absolute-end-time, disable timeout before commit not after.

Only affects machines where MAXALIGN > 4, and is a boundary-condition
case even there, but still surprising that it's not been identified
before.  Also reduce tuple chain move give-up messages from WARNING
to DEBUG1, since they are not unexpected conditions.

conform to C99's brain-dead notion of how inline functions should work.

returning an exception when this method was called.
