Come to think of it, applying ON INSERT/UPDATE/DELETE rules to
inheritance tree members is a bit problematic too. If you do
"UPDATE parent SET ..." then any ON UPDATE rules on the child
table are ignored (since the rewriter considers only "parent").
This probably doesn't lead to any system malfunctions, but
users might find it surprising. I bet we don't document that
adequately.
