Specifies the TCP port or neighborhood Unix area socket file extension on which the server is listening for connections. Defaults to your PGPORT setting variable, if established, or simply a compiled-in default.
In case the involved hosts have adjusted, the relationship info may have to be transformed. It might also be proper to truncate the focus on tables before initiating a new whole desk copy. If customers intend to copy Preliminary information all through refresh they need to develop the slot with two_phase = Phony. After the Original sync, the two_phase solution will be quickly enabled with the subscriber When the membership had been at first created with two_phase = genuine option.
the choice archive file formats has to be used with pg_restore to rebuild the database. they permit pg_restore to generally be selective about what on earth is restored, or maybe to reorder the goods before being restored. The archive file formats are made to be moveable across architectures.
probably the most flexible output file formats would be the “customized” structure (-Fc) and also the “Listing” format (-Fd). They allow for range and reordering of all archived merchandise, support parallel restoration, and so are compressed by default. The “Listing” structure is the only structure that supports parallel dumps.
usually do not dump the contents of unlogged tables and sequences. This option has no impact on whether or not the table and sequence definitions (schema) are dumped; it only suppresses dumping the table and sequence facts. details in unlogged tables and sequences is usually excluded when dumping from the standby server.
Dump information as INSERT instructions (as an alternative to duplicate). Controls the most number of rows for every INSERT command. The value specified have to be a range better than zero. Any mistake for the duration of restoring will cause only rows which can be Portion of the problematic INSERT to get missing, instead of your entire desk contents.
. The pattern is interpreted according to the same regulations as for -n. -N could be offered greater than at the time to exclude schemas matching any of several patterns.
$ pg_restore -d newdb db.dump To reload an archive file to the exact databases it had been dumped from, discarding The existing contents of that database:
If you see something within the documentation that's not appropriate, doesn't match your knowledge with the particular aspect or requires additional clarification, make sure you use this type to report a documentation concern.
can be quite a relationship string. If that's so, link string parameters will override any conflicting command line alternatives.
, ...) VALUES ...). This could make restoration very gradual; it is especially handy for producing dumps that can be loaded into non-PostgreSQL databases. Any error for the duration of restoring will lead to only rows that happen to be Component of the problematic INSERT to become lost, in lieu of your entire table contents.
pg_dump is often a utility for backing up a PostgreSQL databases. It helps make consistent backups even when the databases is being used concurrently. pg_dump doesn't block other consumers accessing the database (readers or writers).
Do not output instructions to established TOAST compression techniques. With this feature, all columns is going to be restored Using the default compression environment.
In case your databases cluster has any community additions to the template1 database, be careful to revive the output of pg_dump into A really empty databases; otherwise you are very likely to get problems because of copy definitions of the included objects.
This option just isn't valuable for any dump which is intended just for disaster recovery. It could be beneficial for any dump used to load a copy on the database for reporting or other read through-only load sharing whilst the initial databases carries on to be current.
