I did just change the planner, but what I don't understand at the moment
is why the results changed for me and not for you.
It looks like it's not actually the join to pg_class that is determining
this, but the plan used for the UPDATE just above it. That involves
only freshly-created tables and so it ought to be pretty much the same
planner problem for everyone. Odd. I'm building now on a Linux machine
to see if I can reproduce your result when using little-endian hardware.
