This is still quite unhelpful; it appears to show normal behavior in
a process that's not the failing one. There is some advice about
collecting useful backtraces at
https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend
I'd counsel the method of enabling core dumps and then attaching
gdb to a core file, rather than dealing with live processes.
