On the same reasoning as in commit 36b931214, forbid using custom oid_symbol macros in pg_type as well as pg_proc, so that we always rely on the predictable macro names generated by genbki.pl. We do continue to grant grandfather status to the names CASHOID and LSNOID, although those are now considered deprecated aliases for the preferred names MONEYOID and PG_LSNOID. This is because there's likely to be client-side code using the old names, and this bout of neatnik-ism doesn't quite seem worth breaking client code. There might be a case for grandfathering EVTTRIGGEROID, too, since externally-maintained PLs may reference that symbol. But renaming such references to EVENT_TRIGGEROID doesn't seem like a particularly heavy lift --- we make far more significant backend API changes in every major release. For now I didn't add that, but we could reconsider if there's pushback. The other names changed here seem pretty unlikely to have any outside uses. Again, we could add alias macros if there are complaints, but for now I didn't. As before, no need for a catversion bump.
