I m using PostgreSQL9.0. It hangs during shutdown. when I used ---pg_ctl stop it hangs and after sometime its displaying msg--- pg_ctl: server does not shut down
and when I used psql its showing----psql: FATAL: the database system is shutting down
and in logs its writing these msgs
DEBUG: postmaster received signal 15 2011-07-14 09:36:00 ETC/GMT LOG: received smart shutdown request
Please tell me how to resolve it???
