vacuum is periodic maintenance. we don't use exilog (we developed our
own quite similar solution just weeks before Tom's announcement :), but
we've had problems with vacuum being unable to do enough garbage
collection so the database was growing steadily no matter what. this
was in PostgreSQL 7.x, we believe it is fixed in 8.1.

never seen that, which PostgreSQL version was that?
