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 ?

ERROR: column c.relhaspkey does not exist at character 33
Below is the query generating the error :
STATEMENT: SELECT c.relname AS table_name, c.relhaspkey AS has_primary_key FROM pg_catalog.pg_class c, pg_catalog.pg_namespace n WHERE c.relkind = 'r' AND c.relnamespace = n.oid AND n.nspname = $1
Any advice on how bad it is and how to get rid of it would be great.
Figure out what is issuing the query and either fix it or upgrade to a version that has been fixed.
Upon googling, I came to know that this error occurs when a connection to higher version Postgres using lower version binaries. 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.
