Jason, I'm thinking that this should be doable rather easily by adding a new
LOOKUP_NO_NON_INTEGRAL mask and passing it down to standard_conversion from 
case_conversion via perform_implicit_conversion_flags.

Then standard_conversion can exclude all such non-integral conversions, eg, for
this specific testcase, return NULL from line #1332 because fcode == REALTYPE
&& (flags & LOOKUP_NO_NON_INTEGRAL)).

Makes sense?
