Extend the BKI infrastructure to allow system catalogs to be given
hand-assigned rowtype OIDs, even when they are not "bootstrapped" catalogsthat have handmade type rows in pg_type.h. Give pg_database such an OID.Restore the availability of C macros for the rowtype OIDs of the bootstrappedcatalogs. (These macros are now in the individual catalogs' .h files,though, not in pg_type.h.)This commit doesn't do anything especially useful by itself, but it'snecessary infrastructure for reverting some ill-considered changes inrelcache.c.
