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 in a
19 : : * cluster, they can diverge due to CLUSTER, REINDEX, or VACUUM FULL. We
20 : : * control assignments of pg_class.relfilenode because we want the filenames
21 : : * to match between the old and new cluster.
22 : : *
23 : : * We control assignment of pg_tablespace.oid because we want the oid to match
24 : : * between the old and new cluster.
25 : : *
26 : : * We control all assignments of pg_type.oid because these oids are stored
27 : : * in user composite type values.
28 : : *
29 : : * We control all assignments of pg_enum.oid because these oids are stored
30 : : * in user tables as enum values.
31 : : *
32 : : * We control all assignments of pg_authid.oid because the oids are stored in
33 : : * pg_largeobject_metadata, which is copied via file transfer for upgrades
34 : : * from v16 and newer.
35 : : *
36 : : * We control all assignments of pg_database.oid because we want the directory
37 : : * names to match between the old and new cluster.
