Hmm. The AV launcher is only permitted to touch pg_database.
At the time there were considerable advantages to that restriction,
but subsequent changes (like getting rid of the need for manual
maintenance of pg_attribute entries for bootstrap catalogs) might
mean that it wouldn't be too painful to extend this capability to
pg_authid etc. Could be worth thinking about.
