I followed that up quickly - server 7.0.2, client 7.1RC1. VACUUMed
etc prior to the test. OTOH, since the tests were done multiple
times directly after the other, the underlying infrastructure should
be the same.

BTW I deleted your paragraph above, but I agree about the parameters
and the constant stuff. I will retry with a fixed-value function
just for the completeness of it.
