Yeah, VACUUM doesn't shrink indexes presently (it's on the TODO
list...).

You could try REINDEX to rebuild the indexes, but I'd recommend updating
to 7.1.2 (or soon, 7.1.3) first. I don't recall whether REINDEX is
available/trustworthy in 7.0.
A grottier solution is to DROP and re-CREATE the indexes.
