NEVER kill -9 a postgres process unless you've exhausted all other
possibilities, as it forces a restart of all the other backends as
well.  A plain kill (no -9) is usually all you need, and it doesn't
cause all the other backends to restart and flush all shared memory.

MUCH better way of doing things.
