Btw. canonicalization/rewriting on INSERT is indeed okay.  As long as the hash
tables are deleted after every iteration (or otherwise invalidated).  At least
the now provably false information needs to be removed, which is a bit
difficult to track when you do general rewriting, so invalidating the whole
thing is probably easiest.
