power quoting of all identifiers. This option is suggested when dumping a database from a server whose PostgreSQL important Model is different from pg_dump's, or when the output is meant for being loaded right into a server of a distinct major Edition.
Requesting distinctive locks on database objects even though running a parallel dump could lead to the dump to fall short.
