I cannot use pg_restore v9.6 on a pg_dump v12 because otherwise: pg_restore: [archiver] unsupported version (1.14) in file header The external supplier did PG v9.5 database + pg_dump v12. I would have to do pg_restore v12 (as of pg_dump v12) into my PG v9.6. The version chain would be PG v9.5 => pg_dump v12 => pg_restore v12 => PG v9.6. That's why my question has been: would the whole chain work and is it supported? > -----Ursprüngliche Nachricht----- > Von: Bruce Momjian <bruce@xxxxxxxxxx> > Gesendet: Mittwoch, 29.
