the choice archive file formats need to be used with pg_restore to rebuild the database. they permit pg_restore to get selective about exactly what is restored, or even to reorder the goods before being restored. The archive file formats are intended to be transportable across architectures.
quite possibly the most versatile output file formats would be the “tailor made” structure (-Fc) along with the “directory” structure (-Fd). They allow for selection and reordering of all archived goods, support parallel restoration, and are compressed by default. The “directory” format is the only format that supports parallel dumps.
When dumping rational replication subscriptions, pg_dump will deliver develop membership commands that utilize the connect = Bogus option, making sure that restoring the subscription will not make remote connections for creating a replication slot or for Original table duplicate. this way, the dump is usually restored without having demanding network use of the remote servers. it is actually then up to your consumer to reactivate the subscriptions in a suitable way.
