No, you just need to make sure the postmaster is started under
"ulimit -c unlimited", not "ulimit -c 0" which is the default
under many Linuxen. Adding this to the start script is the
easiest way usually.
If you can't get anything but numbers from gdb's stack trace
then you have a "stripped" executable and you will need to
rebuild to get a useful stack trace.
