Hmm, 64meg should certainly be far past where check_stack_depth will
start to complain, so there's something else going on here. (BUT:
the ulimits you see interactively aren't necessarily what the postmaster
was started under. You might want to confirm that the results are the
same if you put the limits call into the boot script that launches
the postmaster...)
