This provides a convenient way to look up a database's OID. For
example, the query
SELECT * FROM pg_shdepend
WHERE dbid = (SELECT oid FROM pg_database
WHERE datname = current_database());
can now be simplified to
SELECT * FROM pg_shdepend
WHERE dbid = current_database()::regdatabase;
Like the regrole type, regdatabase has cluster-wide scope, so we
disallow regdatabase constants from appearing in stored
expressions.
Bumps catversion.
