Falling back to a disabled pool member, if all others are down?

Hi,   We have round robin load sharing with two pool members. When we need to do some maintenance, we disable the pool member, and wait for all active and persistent connections to be finished.  ...

What about enabling priority groups instead of disabling a node when preparing for a maintenance window? Give the live node a higher priority than the node going into maintenance, and change "priority group activation" to less than one member (or however many members are not going into maintenance)

if the maintenance is done often, you could have "min-active-members" set to 1 at all times, but configure pool members with equal priorities (10 or something - not 0). When you need to do maintenance on a member, modify the priority of that member to a lesser value
