Coming back to this thread after a while.. we have to remove OID on a 6 TB (5 TB of indexes) table and ALTER TABLE is gonna block the table and is gonna take hours...
We operate on pretty much 0 outage.... we do have a passive site on which we will be doing the activity.. if not ALTER TABLE.. is there any other way to achieve this ? I think logical replication does not allow replicating from one table to another ? Regards, Ven On Sun, 16 May 2021 at 11:00 am, David G.

So, might be some job/script in our environment is using 9.5 binaries against 11 version which is generating this error. Will check that out. >
