I can think of three possible reasons:
1. Machine is very busy (check the performance monitoring, and perhaps
grab some sysinternals tools).
2. Locks on system tables (I'm guessing creating a database requires an
exclusive lock on various bits and pieces). Joining pg_locks to pg_class
via oid will show what's locked.
3. System tables / indexes are horribly bloated and need
vacuuming/reindexing. Try a vacuum verbose and see if it mentions lots
of unremovable rows on pg_database or pg_class or some such.
If it's none of the above then it'll require some proper investigation.
