Wouldn't that result in the thread continuously polling the database,
presenting an unreasonable load?

I guess in some cases if you're paranoid about database size and don't
care about performance that might be ok, but ISTM there should at least
be a warning in the docs. Another concern is that running in that mode
could cause an XID rollover relatively quickly.
