Hi Tom,
Thanks for the help! I'm afraid I do not know how to do this. Is there
somewhere that specifically explains how to run a standalone backend under
gdb? How would I set a breakpoint at elog or get a stack trace? Does the
RPM version of Postgres include debugging symbols, or would I need to
compile a separate version?
Thanks!
