I'd use "ulimit -c unlimited", myself, rather than making arbitrary
assumptions about how big the corefile might be.

Also, make sure the ulimit command is effective in the shell that will
actually launch the postmaster.  This can be tricky if your PG launch
script uses "su".  If you're using the RH or PGDG RPMs' initscript,
I'd suggest putting the ulimit command in ~postgres/.bash_profile.
