Can you provide a script or something to reproduce this behavior?

There are a number of people using Postgres with large databases
and not reporting any such problem, so I think there has to be some
special triggering condition; it's not just a matter of things
breaking at a million rows.  Before digging into it, I'd like to
eliminate variables like whether I have the right test case.
