Elsewhere it was argued that tying this to extensions is not
appropriate. I agree.

It depends on how this feature is supposed to be used exactly. A
replication plugin might very well be loaded via
session_preload_libraries and not appear in SQL at all. In that case
you need some C-level hook. In another case, an extension might want to
inspect relation options from user-space triggers. So you'd need to
register some SQL-level function for option validation.

This could end up being two separate but overlapping features.
