Hello,

Getting "MultiXactId 808530957 has not been created yet -- apparent" error
when trying to VACUUM FREEZE big table, about 263m rows. Normal VACUUM runs
fine.
Also tried to recreate the table and there were no errors "create table
my_table_copy as
select * from my_table".

1.Is it data corruption problem?
2.how to diagnose the error and possibly fix?
