If you are trying to delete the entire contents of a table (and are not
using slony replication or similar) then a simple TRUNCATE <tablename>
will achieve the desired result and free up some diskspace.
Alternatively, if you have indexes on the table, you could try to drop
the indexes (if they are bloated, you can probably regain some diskspace
that way). Delete the rows you need and then create the indexes anew.
