I've took a look into the patch again.

The behavior and integration with the connection state machine look correct, 
and the tests + docs are in good shape. Some notes:
1. Use a dedicated default "0" for check_all_addrs (not DefaultLoadBalanceHosts,
   this one is used for load balancing, need more "0").
2. Guard the two strcmp(conn->check_all_addrs, "1") uses so they are safe when
   conn->check_all_addrs is NULL.
3. Fix the test typos in 008 (standby_expeect_traffic and the three “on node1”
   messages).
4. Parse check_all_addrs once into a bool (like load_balance_type) and use that
   in the connection path for consistency and clarity.

Now about important part: is the name "check_all_addrs" good?
I've asked LLM after explaining it what the feature does. PFA attached output.

Personally, I like "try_all_addrs".

It's a bit unclear to me how randomization (load balancing) on different
addresses should work.
