    # With the timeout connect 5 secs,

    # of 3 connection attempts waiting 5s each time before giving up on the server,
    # for a total of 15 seconds.

    # timeout client and server govern the maximum amount of time of TCP inactivity.
    # The server node may idle on a TCP connection either because it takes time to
    # execute a query before the first result set record is emitted, or in case of
    # some trouble on the server. So these timeout settings should be larger than the
    # time to execute the longest (most complex, under substantial concurrent workload)
    # query, yet not too large so truly failed connections are lingering too long
    # (resources associated with failed connections should be freed reasonably promptly).
