The autovacuum daemon has a lot of settings, it's possible that you simply
don't have it configured aggressively enough.

Please review the documentation and consider the fact that the default
settings are very conservative:
http://www.postgresql.org/docs/8.1/static/runtime-config-autovacuum.html

Additionally, you're missing 8 bug fixes in your version, I highly
recommend updating to 8.1.10 immediately.
