The usual remedy of walking away from the problem and coming back fresh helped me realize my stupid mistake. I still believe in sanity clauses, so I have a little more finessing to do, but the posted code works. Implements uuid_generation functions which return bytea values, a function to convert the bytea values to the canonical hex form, and a function to extract the time from time-based uuids. If you can use this, please do.
