If postmaster is running, start psql in one window, then find the PID
of the postgres process used by psql using
SELECT pg_backend_pid()
. Use a debugger to attach to the postgres PID. You can set

psql. This will cause startup to delay for n seconds so you can attach
to the process with the debugger, set any breakpoints, and continue
