Re: Postgresql version of SQL Server Availability Groups?

Hello,

I confirm that pg_pool is a HA solution.
It handles also load_balancing but it can be disabled : "load_balance_mode
=off "

I recommend pg_pool v4.2 (at least) , much more easy to configure (same
config file on all nodes).

I already use it as a HA solution between 2 nodes (with PG replication),
but be careful with some parameters :
"
failover_when_quorum_exists = on
failover_require_consensus = off
enable_consensus_with_half_votes = on <<===
"
Regards,
Frédéric B.
