If giving a recommendation, shouldn't that be linked only to "i"
instead? If for example numslots = 1024, but that we get an error
after allocating 128 slots because of a lack of fds in the range, then
we would recommend 896, which would still result in an error. I quite
like the suggestion from Andres to keep the message simple with "too
many jobs for this platform's select()". You are indeed right about
the pg_log_fatal() part here, I have changed the patch to do that on
my local branch.
