pg_restore already tries to edit the DROP commands during restore in order to support `--if-exists`. > supporting this option only during initial dump is safer. pg_dump & pg_restores use the same function to inject `IF EXISTS` ( and `DROP .. CASCADE` in this patch`). Supporting this option only during pg_dump may not make it safer, as the logic is the same.
