produce databases foo WITH TEMPLATE template0; any time a data-only dump is decided on and the option --disable-triggers is used, pg_dump emits commands to disable triggers on user tables in advance of inserting the data, and then instructions to re-help them once the information has long been inserted.

don't dump the contents of unlogged tables and sequences. this feature has no impact on whether the table and sequence definitions (schema) are dumped; it only suppresses dumping the table and sequence data. details in unlogged tables and sequences is always excluded when dumping from the standby server.
Dump facts as INSERT instructions (rather then duplicate). This will make restoration quite slow; it is especially valuable for producing dumps which can be loaded into non-PostgreSQL databases. Any mistake for the duration of restoring will trigger only rows that are A part of the problematic INSERT to be missing, rather than the entire table contents.
. The sample is interpreted based on the very same regulations as for -n. -N is often supplied over after to exclude schemas matching any of many styles.
$ pg_restore -d newdb db.dump To reload an archive file to the very same database it was dumped from, discarding The present contents of that databases:
this feature is pertinent only when creating a info-only dump. It instructs pg_dump to include commands to temporarily disable triggers to the goal tables though the info is restored.
hardly ever challenge a password prompt. If your server necessitates password authentication in addition to a password will not be readily available by other suggests for instance a .pgpass file, the link attempt will are unsuccessful. this selection may be practical in batch Work and scripts where by no person is existing to enter a password.
Requesting distinctive locks on databases objects when running a parallel dump could trigger the dump to are unsuccessful. The key reason why would be that the pg_dump leader procedure requests shared locks (accessibility SHARE) within the objects the employee processes are going to dump later on as a way to be sure that nobody deletes them and helps make them disappear whilst the dump is working. If A further consumer then requests an exclusive lock over a table, that lock won't be granted but will likely be queued watching for the shared lock from the leader process to be unveiled.

make use of a serializable transaction with the dump, to make certain that the snapshot used is in step with later on databases states; but do this by looking ahead to some extent in the transaction stream at which no anomalies could be current, so that There is not a hazard of the dump failing or producing other transactions to roll back again using a serialization_failure. See Chapter thirteen To find out more about transaction isolation and concurrency control.
