Description:
Hi,
I'm using a lot the logical replication.
I have to do some DDL changes, via an automatic process, on the primary.
That process drop the existing publication, which will stop the
subscription.
I kept the LSN information on the primary, perform the DDL changes on the
replica.
Than I recreate the publication, use the pg_replication_slot_advance using
the savec LSN.
When I re-enable the subscription, I have an error message in the postgres
log saying that the publication doesn't exist. However, it does have the
same name.
Can a note be added on the "DROP PUBLICATION" page to mention that dropping
a publication will compromise the logical replication process event if the
publication is recreated with the same name.
Thanks.
