Fix pool_signal.
Previously pool_signal did not set SA_RESTART flag. Thus any system
calls interrupted by a signal does not restart. Some of our code are
prepared so that they restart if a system call is interrupted by a
signal. But not sure all places are prepared too. So add the
flag. Note, PostgreSQL always uses the flag.
