Simon, you can't just command the tide to stop coming in while you do
something that no one else can see. This patch is perfectly reasonable,
not at all invasive, and a clear improvement over the way the code was
before. If you can improve on it further, fine, but we're not going to
declare the code off-limits while waiting for an unspecified patch with
no firm delivery date.

regards, tom lane
