Um, well, that depends a lot on which PG version the OP is running
(which he didn't say).  The pre-9.0 implementation of VACUUM FULL
was notorious for creating index bloat, because it shuffled heap
entries around to compact heap space, but created an additional
index entry for each such heap-tuple motion.
