If it were true, it would be in the documentation.

The reason for suggesting that you use the newer pg_dump during a
version upgrade is that the newer version might have bug fixes that
your current version lacks.  In the absence of bugs, however, pg_restore
is supposed to read dump files produced by older versions of pg_dump.
If it fails to, that in itself is a filable bug.
