I have a question, I have found a Citus extension which is recommended for a replication of data between multi-master nodes (I was using Galera Cluster prior to PostgreSQL).
However I cannot find any example of how to replicate tables without creating any additional tables (distributed) as replication has to work without any modification of C# code that is using PostgreSQL as a database.
It has to work in a same way as Galera Cluster (multi-master replication between nodes).
Perhaps I've tried wrong extension, but I've tried to review the options for 3 days and seemed like a good idea.
Perhaps someone could give the recommendation for a good extension that can offer multi-master replication without any additional change in existing queries that are used by our software.
