If that doesn't happen, the disk goes from 10% full to 95% full within 2 days (and it's a 90GB disk...with the database being a 2MB download after dump), and the CPU goes from running at around a 2% load to a 99+% load right away (the stats look like a square wave).
Q: what have you got the FSM parameters set to?
Q: what exactly is bloating? Without knowing which tables or indexes are growing, it's hard to speculate about the exact causes. Use du and oid2name, or look at pg_class.relpages after a plain VACUUM.
It's likely that the real answer is "you need to vacuum more often than every six hours", but I'm trying not to jump to conclusions.
