11 * To simplify the upgrade process, we force certain system values to be
12 * identical between old and new clusters:
13 *
14 * We control all assignments of pg_class.oid (and relfilenode) so toast
15 * oids are the same between old and new clusters. This is important
16 * because toast oids are stored as toast pointers in user tables.
17 *
18 * While pg_class.oid and pg_class.relfilenode are initially the same
19 * in a cluster, they can diverge due to CLUSTER, REINDEX, or VACUUM
20 * FULL. In the new cluster, pg_class.oid and pg_class.relfilenode will
21 * be the same and will match the old pg_class.oid value. Because of
22 * this, old/new pg_class.relfilenode values will not match if CLUSTER,
23 * REINDEX, or VACUUM FULL have been performed in the old cluster.
24 *
25 * We control all assignments of pg_type.oid because these oids are stored
26 * in user composite type values.
27 *
28 * We control all assignments of pg_enum.oid because these oids are stored
29 * in user tables as enum values.
30 *
31 * We control all assignments of pg_authid.oid for historical reasons (the
32 * oids used to be stored in pg_largeobject_metadata, which is now copied via
33 * SQL commands), that might change at some point in the future.

572 * be restored properly by the binary-upgrade restore script. Likewise for
573 * user-database datfrozenxid/datminmxid. However, if we're upgrading from a
574 * pre-9.3 database, which does not store per-table or per-DB minmxid, then
575 * the relminmxid/datminmxid values filled in by the restore script will just
576 * be zeroes.
577 *
578 * Hence, with a pre-9.3 source database, a second call occurs after
579 * everything is restored, with minmxid_only = true. This pass will
580 * initialize all tables and databases, both those made by initdb and user
581 * objects, with the desired minmxid value. frozenxid values are left alone.
