This is more or less a necessary consequence of the fact that _init
functions are now allowed to add background workers. If there is any
code today that expects MaxBackends to be correct at
preload_shared_libraries time, it's already been broken irretrievably
by the bgworkers patch; and we'd be well advised to make that breakage
obvious not subtle.
So I'm +1 for Heikki's proposal as well.
