Output a Listing-format archive ideal for input into pg_restore. this can develop a directory with 1 file for every table and enormous object staying dumped, plus a so-referred to as desk of Contents file describing the dumped objects in the machine-readable structure that pg_restore can examine.
In the situation of a parallel dump, the snapshot name outlined by this selection is applied rather then using a different snapshot.
These statements will fall short once the script is run Until it is actually commenced by a superuser (or the exact same user that owns all the objects inside the script). to generate a script which might be restored by any person, but will give that person possession of each of the objects, specify -O.
parameter is interpreted as a sample in accordance with the exact rules employed by psql's \d instructions (see Patterns), so a number of extensions may also be chosen by writing wildcard people while in the sample.
will not dump the contents of unlogged tables and sequences. this feature has no effect on whether or not the table and sequence definitions (schema) are dumped; it only suppresses dumping the desk and sequence information.

Consequently every other usage of the table won't be granted either and will queue once the exceptional lock request. This features the worker course of action seeking to dump the desk. Without any safeguards This may be described as a typical deadlock situation. To detect this conflict, the pg_dump employee approach requests another shared lock using the NOWAIT choice. In case the employee system is not really granted this shared lock, any individual else needs to have requested an exceptional lock in the meantime and there's no way to continue Using the dump, so pg_dump has no option but to abort the dump.
