commit    abcff550b1930f1e02b69f3f844eb071d3b18ec8

    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.
