probably the most versatile output file formats are definitely the “customized” format (-Fc) and the “Listing” format (-Fd). they permit for choice and reordering of all archived goods, assistance parallel restoration, and therefore are compressed by default. The “directory” format is the only format that supports parallel dumps.
When dumping logical replication subscriptions, pg_dump will make develop SUBSCRIPTION instructions that utilize the link = false alternative, to ensure that restoring the membership does not make distant connections for developing a replication slot or for initial desk copy. this way, the dump might be restored with no demanding community entry to the remote servers. it truly is then up on the user to reactivate the subscriptions in an appropriate way.
start the output which has a command to build the databases by itself and reconnect to the established databases. (by using a script of this form, it would not issue which database from the spot set up you connect to before working the script.
this feature is helpful when needing to synchronize the dump by using a sensible replication slot (see Chapter forty nine) or by using a concurrent session.

(yet another way to get the exact result's to set the PGCLIENTENCODING natural environment variable to the desired dump encoding.) The supported encodings are described in part 24.three.one.
Requesting unique locks on databases objects although running a parallel dump could lead to the dump to fall short. The explanation is that the pg_dump chief course of action requests shared locks (ACCESS SHARE) within the objects the employee processes are likely to dump later on if you want to make sure that nobody deletes them and would make them disappear although the dump is working. If One more shopper then requests an exceptional lock with a table, that lock won't be granted but will likely be queued looking ahead to the shared lock of the chief procedure being introduced.

this selection is not really effective for a dump which is meant just for disaster Restoration. it may be valuable for your dump used to load a duplicate from the databases for reporting or other browse-only load sharing when the original database carries on to become up to date.
Use a serializable transaction for the dump, to ensure that the snapshot made use of is per afterwards databases states; but do this by expecting a degree in the transaction stream at which no anomalies is often present, to ensure there isn't a chance of the dump failing or triggering other transactions to roll again using a serialization_failure. See Chapter 13 for more information about transaction isolation and concurrency Handle.
