+ * To simplify the upgrade process, we force certain system values to be
+ * identical between old and new clusters:
+ *
+ * We control all assignments of pg_class.oid (and relfilenode) so toast
+ * oids are the same between old and new clusters. This is important
+ * because toast oids are stored as toast pointers in user tables.
+ *
+ * While pg_class.oid and pg_class.relfilenode are initially the same
+ * in a cluster, they can diverge due to CLUSTER, REINDEX, or VACUUM
+ * FULL. In the new cluster, pg_class.oid and pg_class.relfilenode will
+ * be the same and will match the old pg_class.oid value. Because of
+ * this, old/new pg_class.relfilenode values will not match if CLUSTER,
+ * REINDEX, or VACUUM FULL have been performed in the old cluster.
+ *
+ * We control all assignments of pg_type.oid because these oids are stored
+ * in user composite type values.
+ *
+ * We control all assignments of pg_enum.oid because these oids are stored
+ * in user tables as enum values.
+ *
+ * We control all assignments of pg_authid.oid because these oids are stored
+ * in pg_largeobject_metadata.
