It'll get truncated by integer division. I wouldn't mind if someone
proposed a patch to create a warning or error in this case, but I
wanted to keep the initial version simple.
I'd recommend against that. Apple recently changed OS X so that
it rejects SHMMAX settings that aren't an exact multiple of
something-or-other, and I've found that to be a *serious* PITA.
Of course part of the problem is that there's no helpful message,
but it's still a big loss from a usability standpoint, and quite
unnecessary (every other Unix seems willing to round off...)
One thought is that maybe we should round up not down? I'm having
a hard time making a specific case either way, though.
Rounding up would have the advantage that you could just specify "0"
in the config file, and have postgres use the smallest value possible.
