in various places that were previously doing ad hoc pg_database searches. This may speed up database-related privilege checks a little bit, but the main motivation is to eliminate the performance reason for having ReverifyMyDatabase do such a lot of stuff (viz, avoiding repeat scans of pg_database during backend startup). The locking reason for having that routine is about to go away, and it'd be good to have the option to break it up.
