Dear Sir,

Startup time of a clean shutdown database is constant. But we still
face problem when it comes to shutting down. PostgreSQL waits
for clients to finish gracefully. till date i have never been able to
shutdown
quickly (web application scenerio) and i tend to do pg_ctl -m immediate stop
mostly.
