They shouldn't; the Notes subsection in the psql reference page says
<para><application>psql</application> works best with servers of the same
or an older major version. Backslash commands are particularly likely
to fail if the server is of a newer version than
<application>psql</application>
itself. However, backslash commands of the <literal>\d</literal> family
should
work with servers of versions back to 9.2, though not necessarily with
servers newer than <application>psql</application> itself. The general
functionality of running SQL commands and displaying query results
should also work with servers of a newer major version, but this cannot
be guaranteed in all cases.
</para>
so the version check is definitely needed.
Thanks
