The second was in fact the wording I had in mind, sorry for not being
clear.  As to the first, the question is whether a log message at that
specific point has any use.  It's not "completion of recovery", exactly,
since we go through that spot whether it's a normal startup or recovery
(and there is another log message when we actually do any WAL replay).
AFAICS it's a fairly randomly chosen place in a long sequence of Things
That Must Happen.  Part of the reason Markus is seeing a race condition
is that this isn't the last thing done before the startup subprocess
exits --- see BootstrapMain.  So I'm for just getting rid of it.
        regards, tom lane
