Hi Andres,
I install pageinspect and create the function, but it returns is null:
select * from check_rel('fn06t') limit 100;
blockno | lp | xmin
---------+----+------
(0 rows)
Other affected table:
vacuum verbose fn06t4;
INFO: vacuuming "public.fn06t4"
ERROR: found multixact 68834765 from before relminmxid 73262006
production=# select * from check_rel('fn06t4') limit 100;
blockno | lp | xmin
---------+----+------
(0 rows)
Best regards,
Alexandre
