True, but if you expect the tables to grow again it's generally
better to leave the space allocated to PostgreSQL than to make it
give it back up to the OS for the moment and have to go ask for it
again later.
If you don't expect PostgreSQL to need the space again and you want
to release it back to the OS, prior to release 9.0 it is usually
better to use CLUSTER than to use VACUUM FULL and REINDEX.
