My recollection is that that change was associated with some pretty
significant revisions to the postmaster state machine. I'm concerned
about the risks involved in back-patching that. This seems to be a
corner case with pretty minimal consequences anyway, so I'm inclined
to leave 8.2 alone.
Now, if I'm wrong about that and you can produce a simple and obviously
correct patch for 8.2, go ahead.
