But you couldn't grant someone implicit membership either, because
then it wouldn't be implicit. So maybe something like this:
pg_database_owner is a predefined role for which membership consists,
implicitly, of the current database owner. It cannot be granted
membership in any role, and no role can be granted membership in
pg_database_owner. However, like any role, it can own objects or
receive grants of access privileges. Consequently, once
pg_database_owner has rights within a template database, each owner of
a database instantiated from that template will exercise those rights.
Initially, this role owns the public schema, so each database owner
governs local use of the schema.
