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. regards, tom lane
