Ok, I will try to explain my environment.
I want to have a high availability environment in active/active mode. I´m
building a cluster with 2 or more nodes, with Apache and JBOSS. Apache works as
proxy and balancer and JBOSS serves my application. I have high availability in
JBOSS thanks to

Hi,
I just tried a POC with PostgreSQL's streaming replication for the use case of
my product. Since streaming replication is master-slave, when failover occurs
there are some configuration changes required to promote slave to master. Also,
my requirement is to failback to old master again
Update :
My query SELECT * FROM v_actor JOIN f_intervenant_ref ON (actor_id =
ir_actor_id) WHERE ir_dos_id = '5226' took 7 secs.
If I substitute the _RETURN rule for the view and add the above join, it takes
31 ms.

Some weird edge cases to be careful about: activities that cross midnight.
Activities that last more than one full day,

I think you just SUM() over the intersection between each hourly window

Craig,
Your response was very helpful, thank you.
I was looking at some of the standard bits in Postgres like
txid_current_snapshot() and txid_snapshot_xmin(). Can the results from
txid_snapshot_xmin be used with pg_get_transaction_committime() to get the
latency?
Thanks again,

Hi Pushkar,
1. How does the initial data sync of node3 with node2 takes place?
2. For node3 and replication data to/from node2, does node2 needs a
restart or it is not required?
Have you looked at?

Kind regards/met
The documentation says that all the existing nodes need to be restarted while
adding a new node since the existing nodes need to establish connection to the
new node. However, this doesn’t seem feasible for production deployments
because existing nodes might be serving clients which would fail
