Обсуждение: pgsql: Don't set the signal handler for SIGQUIT on Windows.

Log Message:
-----------
Don't set the signal handler for SIGQUIT on Windows. Buildfarm shows that
reinstalling the default signal handler doesn't work as it is on Windows.
Presumably core dumps on SIGQUIT are not a problem on Windows, so rather
than figure out what header files or other changes are required to make it
work, just don't bother.
