Обсуждение: The -o command line option of pg_dump for a database using foreign keys

PostgreSQL 7.1.2 Administrator's Guide says as follows:

    Chapter 8. Backup and Restore
    8.1. SQL Dump

    Important: When your database schema relies on OIDs (for instances as
    foreign keys) you must instruct pg_dump to dump the OIDs as well. To do
    this, use the -o command line option.

Is the -o option still required for 7.1.2 version for a database using foreign
keys?


Kind regards,

Only if you use object ids (OID's).
