What I'd recommend doing is gdb'ing the core dump file to get a stack
trace; that would give us some clue what's wrong. And you could do
"p debug_query_string" to see what query made it crash.
If you do not find a core file in the database subdirectory
($PGDATA/base/yourdbnumber/core) then you are probably running the
postmaster with "ulimit -c 0" which disables core dumps. Restart
it with environment "ulimit -c unlimited".
