Hello!
The backend signals code today uses pqsignal() instead of signal() at all places. But it uses kill() and sigsetmask() (through the macro PG_SETMASK) directly.
I propose to change this to pqkill() and pqsigsetmask(). In pqsignal.h, these would be #define:d back to kill() and setsigmask() for the normal method, but would be functions on win32.
Sounds logical and more consistent than it is now.
While talking about it, I think our usage of signals is way overloaded anyway. Any ideas how to replace it all with just one signal and a regular message queue?
