Alternatively and maybe faster, just run psql under gdb to start with: $ gdb /path/to/psql gdb> run arguments-for-psql-go-here ... interact with psql normally, provoke crash gdb will report SIGSEGV and give you a prompt: gdb> bt ... stack trace printed here ... gdb> quit $ If the stack trace contains only numeric addresses then it won't be any help; in that case please recompile psql with debugging support so you can get a useful trace. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
