Are you storing '12 feet' as a string? That seems awfully unstructured
for data that you'd like to do calculations on.
I seem to recall that someone had come up with a datatype that would
store numbers with units attached, which seems like what you want here.
Check the PG list archives, and/or poke around on pgfoundry and gborg.
