Method 2: PostgreSQL Synchronous Replication. Setting up PostgreSQL sync replication mainly follows the steps similar to those discussed in … WebI found a variable that should probably be related to that, but does not have any oficial explanation on description field ('cross_replica_sync', True, ''). So, finally, my question is that if I use the parameter server mode, but have the cross_replica_sync set to false, does that mean that my updates are going to be executed asynchronously?
