pg_restore does its best to be backwards compatible to try and load old
dump files. So I would just try it and see with PG12.
However, there is a chance, depending on what was in that old version, that
it may not restore without error. In that case, you could bring up a 9.3
cluster and restore the dump there. Then use the pg_dump binary from PG12
to create a new dump. The newer pg_dump binaries running on old servers try
and convert things as needed.
