There is that. I wondered before if it would be worth the trouble to
invent a distinct pg_rewrite.ev_type value for these things, ie the rule
would be something like "ON REFRESH DO INSTEAD ...". On balance that
seems like it would force a lot of additional code changes for
questionable benefit, though.
