Sig 11 is bad, mkay?  basically it means the postgres process is
crashing.  It could be crashing because of a corrupted / buggy
executable, or bad hardware.  Do you have another machine you trust to
move your pgsql database to?   Because I wouldn't trust the one it's
on right now until you can pull it from service, confirm the pg
binaries aren't corrupted, and test your hardware.
