I was inspired to do a write-up on this for the Wiki:
https://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Linux/BSD#Dumping_a_page_image_from_within_GDB
Seems like a good idea to centralize knowledge of backend
instrumentation that's useful for bug reports, even beyond GDB.
