Patch applies. Do not forget to regenerate configure to test...
I've compiled and run with both ppoll & select options without issues.
Two quite minor style comment (at least 2 instances):
if (cond) return false; else return true;
ISTM that the simpler the better:
return !cond;
Fixed.
Also ISTM that the following does not comply with pg C style expectations
(idem, 2 instances):
} else {
Fixed.
Also fixed issue with 'timeout' not being passed as NULL when no timeout time.

Use pselect(2) not select(2), if available, to wait in postmaster's loop.
