Output a directory-structure archive ideal for input into pg_restore. this will likely make a directory with a person file for each table and enormous item becoming dumped, furthermore a so-identified as desk of Contents file describing the dumped objects inside of a equipment-readable format that pg_restore can go through.
In the case of a parallel dump, the snapshot title outlined by this option is utilized instead of taking a whole new snapshot.
These statements will fail in the event the script is operate Until it can be began by a superuser (or the same consumer that owns all the objects from the script). to produce a script that can be restored by any person, but will give that consumer possession of every one of the objects, specify -O.
With zstd compression, extended manner may well Increase the compression ratio, at the expense of increased memory use.
When dumping sensible replication subscriptions, pg_dump will make build SUBSCRIPTION commands that utilize the connect = Fake solution, in order that restoring the membership won't make remote connections for making a replication slot or for Original table duplicate. That way, the dump might be restored with out necessitating network use of the remote servers. it can be then up for the user to reactivate the subscriptions in an acceptable way.
commence the output by using a command to produce the database itself and reconnect towards the designed database. (that has a script of this manner, it will not matter which database while in the place set up you connect with right before working the script.
never hold out endlessly to amass shared desk locks at the start of the dump. as an alternative are unsuccessful if unable to lock a desk inside the specified timeout
To carry out a parallel dump, the database server really should assist synchronized snapshots, a feature which was launched in PostgreSQL 9.2 for เว็บตรงลิขสิทธิ์แท้ Main servers and 10 for standbys. using this type of aspect, database customers can make certain they see the exact same details set Regardless that they use diverse connections.
this selection is suitable only when making a data-only dump. It instructs pg_dump to include commands to quickly disable triggers on the concentrate on tables when the info is restored.
you'll be able to only use this selection Along with the Listing output structure because this is the only output format where by a number of procedures can compose their data concurrently.
Requesting special locks on database objects whilst running a parallel dump could lead to the dump to are unsuccessful. The explanation would be that the pg_dump chief approach requests shared locks (ACCESS SHARE) on the objects the worker procedures will dump later if you want to make certain that no one deletes them and makes them go away though the dump is functioning. If A different consumer then requests an distinctive lock on the table, that lock won't be granted but are going to be queued watching for the shared lock from the chief process to be released.
This is certainly the same as the -t/--table option, apart from that Furthermore, it involves any partitions or inheritance child tables of the desk(s) matching the sample
When applying wildcards, be cautious to quote the pattern if wanted to prevent the shell from increasing the wildcards; see Examples beneath.
Do not output instructions to pick tablespaces. With this feature, all objects will likely be developed in whichever tablespace is the default for the duration of restore.
For the customized and Listing archive formats, this specifies compression of specific desk-facts segments, as well as default should be to compress employing gzip in a reasonable stage. For basic textual content output, environment a nonzero compression degree triggers the whole output file for being compressed, as though it had been fed by gzip, lz4, or zstd; though the default is never to compress.
When employing wildcards, be cautious to estimate the sample if desired to stop the shell from expanding the wildcards.
