They allow แทงบอลออนไลน์ for range and reordering of all archived items, assistance parallel restoration, and so are compressed by default. The “directory” format is the only format that supports parallel dumps.
When dumping sensible replication subscriptions, pg_dump will produce develop SUBSCRIPTION commands that use the join = false option, in order that restoring the subscription won't make remote connections for making a replication slot or for Preliminary table copy. That way, the dump is usually restored with out requiring network usage of the remote servers. it really is then up on the user to reactivate the subscriptions in an acceptable way.
Dump facts as INSERT instructions (rather then duplicate). This can make restoration extremely gradual; it is principally useful for earning dumps that can be loaded into non-PostgreSQL databases. Any mistake through restoring will result in only rows which can be A part of the problematic INSERT to get lost, rather then all the desk contents.
If no compression amount is specified, the default compression degree might be applied. If merely a level is specified without having mentioning an algorithm, gzip compression is going to be utilized if the extent is larger than 0, and no compression will probably be employed if the level is 0.
To carry out a parallel dump, the database server must assistance synchronized snapshots, a feature which was released in PostgreSQL 9.2 for Most important servers and ten for standbys. using this type of characteristic, databases consumers can make sure they see the same knowledge established While they use unique connections.
. The sample is interpreted according to the exact same principles as for -t. -T may be supplied more than after to exclude tables matching any of quite a few styles.
power quoting of all identifiers. this selection is suggested when dumping a databases from the server whose PostgreSQL significant Variation differs from pg_dump's, or if the output is meant being loaded into a server of a special main version.
However, the tar structure doesn't help compression. Also, when working with tar format the relative get of desk info goods cannot be changed all through restore.
