This made the command line simple but I'm having second thoughts about it: if anything inside the backend tries to read stdin or write stdout, unpleasant things will happen. It might be better to not reassign the pipe FD numbers. In that case we'd have to pass them on the command line, so that the syntax would be something like "postgres --child 4,5 -D pgdata ...".
Would it be sufficient to just hard-code the FD's to use? I'm not sure why someone would need to change them, so long as we steer clear of STD(IN|OUT|ERR)... -- Jim C.
