Hi Craig,

So, is it safe to drop those list from this query output?

select riname from pg_replication_identifier where riname not in 
(select external_id from pg_replication_identifier_progress);

I cannot read pg_get_replication_identifier_progress function, is it likely c function?

Hi Craig,

Thanks again for pointing to inactive replication slot.
After inactive replication slot been dropped, the relfrozenxid now moving.

I wonder if  replication identifier will have some issue if left un-chained? since at other side there are inactive replication identifier.

No, that's harmless.

However, if there's still an "other side" at all, you presumably have broken replication.
