With zstd compression, very long mode might improve the compression ratio, at the expense of amplified memory use.
Note that if you utilize this feature at present, you most likely also want the dump be in INSERT structure, because the duplicate FROM for the duration of restore isn't going to assist row protection.
Output SQL-standard established SESSION AUTHORIZATION commands in place of ALTER operator commands to ascertain item possession. This helps make the dump more criteria-compatible, but according to the heritage from the objects inside the dump, might not restore appropriately.
If no compression degree is specified, the default compression stage will probably be employed. If only a stage is specified without mentioning an algorithm, gzip compression might be made use of if the extent is larger than 0, and no compression will likely be used if the level is 0.
. The pattern is interpreted according to the same regulations as for -t. --exclude-desk-facts is usually presented over after to exclude tables matching any of several styles.

pressure quoting of all identifiers. this feature is usually recommended when dumping a database from a server whose PostgreSQL important Edition is different from pg_dump's, or if the output is intended to become loaded right into a server of a different key Variation.
Requesting unique locks on database objects although working a parallel dump could cause the dump to are unsuccessful. The reason would be that the pg_dump leader approach requests shared locks (entry SHARE) to the objects which the employee processes will dump later to be able to ensure that no person deletes them and would make them disappear while the dump is working. If A different consumer then requests an distinctive lock on a desk, that lock won't be granted but will be queued expecting the shared lock in the leader procedure to be produced.
When dumping information for any desk partition, make the duplicate or INSERT statements focus on the foundation of the partitioning hierarchy that contains it, instead of the partition alone. This results in the right partition for being re-identified for each row when the information is loaded.
usually do not output commands to established TOAST compression methods. With เว็บตรง this option, all columns will probably be restored With all the default compression environment.
Specify the compression strategy and/or perhaps the compression level to utilize. The compression approach could be set to gzip, lz4, zstd, or none for no compression. A compression detail string can optionally be specified.
For the personalized and directory archive formats, this specifies compression of unique table-facts segments, and also the default would be to compress utilizing gzip at a reasonable stage. For plain text output, environment a nonzero compression stage triggers your complete output file to generally be compressed, as though it were fed through gzip, lz4, or zstd; however the default is to not compress.
this selection is related only when dumping the contents of the desk that has row protection. By default, pg_dump will established row_security to off, to make sure that all info is dumped in the desk.
