How do I make a backtrace?
- if you have coredump, just execute gdb /PATH1/postgres gdb /PATH2/core
and type bt. Linux doesn't make core by default, so you allow to do it
by ulimit -c unlimited for postgresql user
- connect to db, and attach gdb to backend process: gdb /PATH1/postgres
BACKEND_PID and type run in gdb, next, execute CREATE DICTIONARY and
type bt in gdb
I am completely unfamiliar with gdb, but hopefully, this is what you are
after?
(gdb) continue
Continuing.
