The large integer-like value is silently transformed into a float8 by
the scanner (very early in the parsing stage). You have not provided a
function to transform float8 into uint4, which if you do so will fix
your problem. Do a
create function uint4(float8)...
and the type coersion code will understand how to convert one into the
other.
