More improvements of error messages about mismatching relkind 

Follow-up to 2ed532ee8c, a few error
messages in the logical replication area currently only deal with
tables, but if we're anticipating more relkinds such as sequences
being handled, then these messages also fall into the category
affected by the previous patch, so adjust them too.
