* OLD COMMENTS:
* The database's oid forms half of the unique key for the system
* caches and lock tables. We therefore want it initialized before
* we open any relations, since opening relations puts things in the
* cache. To get around this problem, this code opens and scans the
* pg_database relation by hand.
