If we compare two items A and B, with B being (a constant) of a
larger type, then A gets promoted to B's type for comparison if
it's a constant, function, or CAST() column, but B gets demoted
to A's type if A is a (not explicitly CAST()) column. This is
counter-intuitive and not mandated by the standard.
 
Disabling optimisation where it would be lossy so field value
will properly get promoted and compared as binary string (rather
than as integers).
