Yeah, I don't believe it is the same bug. That particular error message
suggests that some part of the planner has dropped the ball in building
target lists for plan nodes, but that could cover a lot of territory.
The fact that Andrew is finding the bug difficult to reproduce reliably
is odd too; maybe an uninitialized-variable problem?
