I don't see any comments in this patch that capture the real
reason for removing pg_replication_origin's TOAST table,
namely (IIUC) that we'd like to be able to access that catalog
without a snapshot.  I think it's important to record that
knowledge, because otherwise somebody is likely to think they
can undo this change for $whatever-reason.
