do you know what query you were making when you ran out of memory? it
-appears- it was a postgres server process that was OOM'd.
what OS and version are you on (OOM seems to imply its likely linux,
since no other OS I'm familiar with would randomly kill processes like
that), what version postgres, etc ?
also, what are the various memory settings in your postgresql.conf
(shared_buffers, work_mem, etc)
