don't dump the contents of unlogged tables and sequences. this feature has no impact on whether the desk and sequence definitions (schema) are dumped; it only suppresses dumping the desk and sequence data. Data in unlogged tables and sequences is often excluded when dumping from a standby server.
Output SQL-normal established SESSION AUTHORIZATION commands in lieu of change OWNER commands to ascertain item possession. This will make the dump far more benchmarks-compatible, but according to the record on the objects inside the dump, won't restore properly.
If no compression level is specified, the default compression level will probably be used. If merely a stage is specified with no mentioning an algorithm, gzip compression are going to be employed if the level is greater than 0, and no compression are going to be utilized if the extent is 0.

A directory format archive is usually manipulated with typical Unix instruments; one example is, documents in an uncompressed archive can be compressed While using the gzip, lz4, or zstd equipment. This structure is compressed by default applying gzip and likewise supports parallel dumps.
power quoting of all identifiers. This option is suggested when dumping a database from the server whose PostgreSQL big Model is different from pg_dump's, or when the output is meant to generally be loaded right into a server of another significant Edition.
Requesting exceptional locks on database objects when jogging a parallel dump could result in the dump to fail. The reason is that the pg_dump leader method requests shared locks (obtain SHARE) to the objects the employee procedures are likely to dump later as a way to make sure that no one deletes them and can make them go away whilst the dump is operating. If One more client then requests an distinctive lock with a desk, that lock won't be granted but are going to be queued watching for the shared lock on the leader system to generally be launched.

Use a serializable transaction to the dump, to ensure that the snapshot made use of is in keeping with later database states; but do that by watching for some extent from the transaction stream at which no anomalies might be present, in order that There's not a hazard in the dump failing or producing other transactions to roll back again that has a serialization_failure. See Chapter 13 For more info about transaction isolation and concurrency Management.
