There's been more contention than one could wish about both what
the behavior should be and how to refactor the code to achieve it.
Nonetheless, I think there is general consensus that the current
behavior isn't very desirable, so if we can reach agreement I think
this should be treated as a bug fix.

It seems like people are not convinced that this cure is better than
the disease.

Yeah. I'm not sure why these have received so little love.
The only one of this ilk that I've personally looked at was

>> * Make message at end-of-recovery less scary

which for me adds far too much complication for the claimed benefit.
Maybe somebody else with a lot more familiarity with the current WAL
code will care to push that, but I'm not touching it. Post-FF
doesn't seem like a good time for it anyway from a risk/reward
standpoint.
