Hi,
Please refer to this scenario where pg_upgrade operation is failing if
the table is create in single-user mode.
PG v13
--connect to PG v13 using single user mode ( ./postgres --single -D
/tmp/data13 postgres )
--create table ( backend> create table r(n int); )
--exit ( ctrl + D)
-- Perform pg_upgrade ( PG v13->PG v15) )(./pg_upgrade -d data13 -D
data15 -b /usr/psql-12/bin -B . )
it will fail with these messages
Restoring global objects in the new cluster ok
Restoring database schemas in the new cluster
postgres
*failure*
Consult the last few lines of "pg_upgrade_dump_14174.log" for
the probable cause of the failure.
Failure, exiting
--cat pg_upgrade_dump_14174.log

pg_restore: creating TABLE "public.r"

Command was:
-- For binary upgrade, must preserve pg_type oid
SELECT
pg_catalog.binary_upgrade_set_next_pg_type_oid('14181'::pg_catalog.oid);
-- For binary upgrade, must preserve pg_class oids and relfilenodes
SELECT
pg_catalog.binary_upgrade_set_next_heap_pg_class_oid('14180'::pg_catalog.oid);
SELECT
pg_catalog.binary_upgrade_set_next_heap_relfilenode('14180'::pg_catalog.oid);
CREATE TABLE "public"."r" (
"n" integer
);
-- For binary upgrade, set heap's relfrozenxid and relminmxid
UPDATE pg_catalog.pg_class
SET relfrozenxid = '492', relminmxid = '1'
WHERE oid = '"public"."r"'::pg_catalog.regclass;
Is it expected ?
