I'm trying to restore a database dumpfile I made of a small 9.3.4 database using pg_dump -Fc -v -f "db.dump" db, but when I try to restore it on the same or on another 9.3.4 system with pg_restore -C -d postgres db.dump I get the following error message: pg_restore: [archiver] unexpected data offset flag 0 Even listing the contents doesn't work: pg_restore -l db.dump pg_restore: [archiver] unexpected data offset flag 0 I couldn't find anything in the documentation about this error message. Is it possible that the dump is corrupted? What can I do to fix this?
