Unfortunately, it didn't work :(
db0=# select * from failing_table where ctid='(3160,31)' for update;
ERROR: MultiXactId 12800 has not been created yet -- apparent wraparound
Since the probability we are into corruption is very high, what if I
\copy all the table but the failing row(s) to an external file, drop and
recreate the table, and then \copy clean data back inside?
Thanks
