This will drop existing connections except for yours:

Query pg_stat_activity and get the pid values you want to kill, then issue SELECT pg_terminate_backend(pid int) to them.

PostgreSQL 9.2 and above:

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'TARGET_DB' ← change this to your DB
 AND pid <> pg_backend_pid();

PostgreSQL 9.1 and below:

SELECT pg_terminate_backend(pg_stat_activity.procpid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'TARGET_DB' ← change this to your DB
 AND procpid <> pg_backend_pid();

Once you disconnect everyone you will have to disconnect and issue the DROP DATABASE command from a connection from another database aka not the one your trying to drop.

Note the renaming of the procpid column to pid. See this mailing list thread.
