Note that ulimit is inherited by child processes; it doesn't apply
system wide. You'll need to set the ulimit somewhere like the postgresql
init script, where the postmaster is a child of the shell in which the
ulimit command is run.

Also, because Debian strips its binaries by default, you might need to
rebuild the postgresql packages with debugging enabled and without
stripping to get a useful backtrace. Worth a try anyway, though.

Does Debian have a repository full of debug symbol packages like Ubuntu
does?
