ERROR: database is being accessed by other users

[wolverine my <wolverine.my@xxxxxxxxx>]

Hi!

I got the following psql's error when executing a script,
ERROR:  database "test" is being accessed by other users

To solve this, I have to disconnect the database connection from the
pgAdmin III.

May I know how can I configure the database to allow multiple user access?
