The alternative archive file formats must be applied with pg_restore to rebuild the database. they permit pg_restore being selective about precisely what is restored, or simply to reorder the objects ahead of remaining restored. The archive file formats are made to be portable across architectures.

When using wildcards, be mindful to quote the pattern if wanted to avoid the shell from expanding the wildcards; see Examples below. The only exception is an empty pattern is disallowed.
. The pattern is interpreted in accordance with the similar rules as for -t. --exclude-desk-information might be offered a lot more than after to exclude tables matching any of many patterns. this feature is beneficial whenever you will need the definition of a specific desk Although you do not need to have the data in it.
for making an empty database with none local additions, duplicate from template0 not template1, one example is:
For that reason any other usage of the desk will not be granted both and will queue once the exceptional lock request. This incorporates the worker method attempting to dump the desk. with none safety measures this would certainly be a common deadlock situation. To detect this conflict, the pg_dump worker method requests A different shared lock using the NOWAIT possibility. If your worker method just isn't granted this shared lock, someone else needs to have requested an special lock Meanwhile and there's no way to continue with the dump, so pg_dump has no choice but to abort the dump.
ship output to the specified file. This parameter might be omitted for file based mostly output formats, during which scenario the normal output is applied.

this feature just isn't beneficial for just a dump which is meant only for disaster Restoration. It could be helpful to get a dump accustomed to load a copy of the databases for reporting or other read-only load sharing even though the initial databases continues to get updated.
When making use of wildcards, be mindful to quote the sample if essential to prevent the shell from expanding the wildcards.
