Let me ask about type coersion.
When you have an int2 column called x, how do you place the conversion
functions when it is being compared to an in4 constant?
x = int2(500)
int4(x) = 500
The first is good for indexing, the second is not. If they are both
variables or both constants, the handling does not matter.
