It doesn't work here and I see the following in src/libpq/crypt.c.
/* If they encrypt their password, force MD5 */
if (isMD5(passwd) && port->auth_method != uaMD5)
{
elog(LOG, "Password is stored MD5 encrypted. "
"'password' and 'crypt' auth methods cannot be
used.");
return STATUS_ERROR;
}
As far as I see, 7.3 forces the use of md5 authentication
implicitly rather than recommending it. Please document
it clearly on the top of the main documents. Otherwise
users would be confused pointlessly.
