Hi There,
We are attempting to upgrade our Postgres databases from 9.5 to 12.5 using pg_upgrade link mode and are facing issues with OIDs.
ALTER TABLE... SET WITHOUT OIDs on the larger tables is taking very long and is locking up the table as well. We do have tables of more than 1 TB of size.
Is there any way to make this complete faster ? Any suggestions would be great.
