Integration
Integration with pg_dump and pg_restore
dbpmda can be used in combination with the pg_dump and pg_restore commands to back up and restore databases. For example, the following command backs up the "my_database" database to a file named "my_backup.dump":
pg_dump -U username my_database > my_backup.dump
The following command restores the "my_database" database from the "my_backup.dump" file:
pg_restore -U username -d my_database my_backup.dump
