Dropped database still shows in the database list.

Hi,
Dropped database 'RestoreDB' is still being listed in pg_database.
Any idea why this behavior is seen ? Also I don't see any open connections
to this database.
pg_stat_activity has no rows for this database.

- *postgres=# create database ResotreDB;*

CREATE DATABASE

- * postgres=# select oid, * from pg_database where datname like
'RestoreDB';*
