Yes, I could see empty value here.

Yes, I can see the following processes still running. I used the command 'ps
-ef |grep postgres' to list.
postgres 3376 1 0 07:20 ? 00:00:00
/mnt/database/pgsql/bin/postgres -D /usr/local/pgsql/data
postgres 3381 3376 0 07:20 ? 00:00:00 postgres: logger process
postgres 3383 3376 0 07:20 ? 00:00:00 postgres: writer process
But why logger and writer process are still running/showing up here for a
very long time after issuing 'service postgresql stop'. What could be the
problem? Also, am sure here that no other clients (database connections)
are connected at this time.
