Well, that's exactly what I'd like to know. The direct cause of the
error is that DROP TABLE is finding that some other backend has a
reference-count hold on a page of the temp table it's trying to drop.
Since no other backend should be trying to touch this temp table,
there's something pretty fishy here.
Given that this is a parallel test, you may be looking at a
low-probability timing-dependent failure. I'd say set up the machine
and run repeat tests for an hour or three ... that's what I plan to do
here.
BTW, what postmaster parameters are you using --- -B and so forth?
