I explained it in another mail. We had quite a few changes we had to make (several hundred man-hours, about half of which was the POSIX layer and the precise time routines). No sense trying to simulate fork() -- it stinks on Win32. The Cygwin and PW32 implementations of fork() are dogs. Smarter folks than us tried it and failed miserably. Why reinvent a broken wheel? We use create process and our own startup code. Our version is competitive with fork() on Linux for spawning tasks and in general the queries run considerably faster. > I know Windows very well, but I have thus far remained > ignorant of PostgreSQL > internals. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
