Assuming you aren't suffering from index bloat, which was a problem in
7.2, this may be normal. To see if you are, try "reindex indexname" and
see if the index shrinks.
Multicolumn indexes being bigger than their table because of the way
they're put together, so it's likely that when you get done reindexing
the index will still be bigger than the table.
