You may be suffering from index bloat. Newer versions mostly deal with
this but old ones don't. Check the data directory for files that keep
growing. Cross-reference with relfilenode in pg_class. Also, vacuuming
once every few hours for such a commonly updated table seems not
enough, maybe you need to do it more often. What about your FSM
settings?
If it's index bloat, simply running REINDEX over the table should fix
it. In general, VACUUM FULL + REINDEX should have pretty much the same
effect as a dump/restore..
Hope this helps,
