What I usually do is
- start a psql session
- in another window, find out the PID of the backend attached
to the psql session, and do
$ gdb /path/to/postgres backend_PID
...
gdb> b errfinish
gdb> cont
- go back to psql session and issue problem command
- when gdb stops execution, do
gdb> bt
... useful printout is here ...
gdb> quit
sure you want to exit? y
