Have you looked into the postmaster log to see *why* it's not shutting
down?

It's not exactly recommended when you don't know what the problem is.

Killing only the postmaster and not its child processes is especially
not recommended --- there are some defenses in place against that,
but nothing that can't be broken by a sufficiently determined DBA.
