This table design is sufficiently ugly and pointless that I feel no deep
remorse over the fact that you can't use an index that way ;-)
Why are you bothering with these divisors? float4 is no larger than
int4 and will eliminate all of these pushups: just store the values
naturally.
If there really is some good reason to use scaled integers, you should
build yourself a scaled-integer datatype.
