the choice archive file formats needs to be utilized with pg_restore to rebuild the databases. they permit pg_restore to get selective about what's restored, and even to reorder the items prior to being restored. The archive file formats are meant to be portable across architectures.
With zstd compression, very long method may possibly improve the compression ratio, at the price of greater memory use.
Do not dump the contents of unlogged tables and sequences. this feature has no effect on whether the desk and sequence definitions (schema) are dumped; it only suppresses dumping the table and sequence information. information in unlogged tables and sequences is always excluded when dumping from a standby server.
Output SQL-regular SET SESSION AUTHORIZATION instructions as opposed to ALTER operator instructions to find out item possession. This tends to make the dump far more expectations-compatible, but dependant upon the heritage of the objects during the สล็อตเว็บตรง dump, might not restore thoroughly.

generate the dump in the required character established encoding. By default, the dump is made in the databases encoding. (yet another way to obtain the exact same result is to established the PGCLIENTENCODING surroundings variable to the desired dump encoding.) The supported encodings are explained in Section 24.3.1.
Requesting unique locks on databases objects although working a parallel dump could lead to the dump to are unsuccessful. The explanation is that the pg_dump leader system requests shared locks (entry SHARE) within the objects which the employee processes will dump later on to be able to be sure that no one deletes them and makes them go away while the dump is working. If An additional consumer then requests an distinctive lock over a table, that lock won't be granted but will be queued awaiting the shared lock on the chief system to generally be produced.
This is often similar to the -t/--table choice, other than that Furthermore, it involves any partitions or inheritance boy or girl tables from the table(s) matching the sample
In the event the consumer doesn't have sufficient privileges to bypass row safety, then an mistake is thrown. This parameter instructs pg_dump to established row_security to on rather, permitting the person to dump the aspects of the contents of the table that they have entry to.
To restore from this kind of script, feed it to psql. Script data files can be employed to reconstruct the database even on other machines and other architectures; with some modifications, even on other SQL databases products and solutions.
with the custom and directory archive formats, this specifies compression of personal table-facts segments, as well as default would be to compress working with gzip in a average amount. For plain textual content output, environment a nonzero compression degree brings about your entire output file being compressed, as if it were fed by means of gzip, lz4, or zstd; though the default is not to compress.
When working with wildcards, watch out to estimate the pattern if needed to circumvent the shell from expanding the wildcards; see Examples down below.
