Something about typing that message jarred by brain to think to try:

VACUUM FULL pets;
VACUUM ANALYZE pets;

Now the new cube-based calculation benchmarks reliably faster. The old
lat/lon systems now benchmarks at 250ms, while the the new cube-based
code bechmarks at 100ms,  over a 50% savings!

That's good enough for me.

However, I'm still interested advice on the other points I snuck into my
last message about joining with ints vs varchars and best use of partial
indexes.
