Use WaitLatch, not pg_usleep, for delaying in pg_sleep().
This avoids platform-dependent behavior wherein pg_sleep() might fail to be
interrupted by statement timeout, query cancel, SIGTERM, etc. Also, since
there's no reason to wake up once a second any more, we can reduce the
power consumption of a sleeping backend a tad.
Back-patch to 9.3, since use of SA_RESTART for SIGALRM makes this a bigger
issue than it used to be.
