The only unsolved issue is the one with underflow checks. I have added

This will behave better for float4:
Datum float4pl(PG_FUNCTION_ARGS)
{
--- float4 arg1 = PG_GETARG_FLOAT4(0);
--- float4 arg2 = PG_GETARG_FLOAT4(1);
+++ double arg1 = PG_GETARG_FLOAT4(0);
+++ double arg2 = PG_GETARG_FLOAT4(1);
double result;
result = arg1 + arg2;
CheckFloat4Val(result,isinf(arg1) || isinf(arg2));
PG_RETURN_FLOAT4((float4) result);
}
