Under load the exec probes timed out at their 1 s default; three misses in a row restart postgres and take the control plane down mid-run. Signed-off-by: Davanum Srinivas <davanum@gmail.com>

Under load the 5 s liveness probe missed 4 of its 6 allowed tries during a close wave; one more miss would have restarted the database mid-run. A slow database must leave the Service, not be killed, so the readiness timeout stays at 5 s. Signed-off-by: Davanum Srinivas <davanum@gmail.com>

The exec probes time out at the 1 s default under load; three misses restart postgres and ateapi loses its connections.
timeoutSeconds: 5, liveness:timeoutSeconds: 10(a close wave under high load missed 4 of the 6 allowed liveness tries at 5 s),failureThreshold: 6on both; periods unchanged.
