When dumping reasonable replication subscriptions, pg_dump will crank out produce membership commands that use the link = false alternative, so that restoring the subscription doesn't make remote connections for creating a replication slot or for initial table duplicate. like that, the dump is often restored with no demanding network access to the distant servers. it is actually then up to your person to reactivate the subscriptions in a suitable way.
Dump facts as INSERT commands (as opposed to COPY). This is likely to make restoration quite gradual; it is mainly handy for producing dumps that could be loaded into non-PostgreSQL databases.
