As I heard, PostgreSQL 9.5 has built in Bi-Direction replication (or need install BDR module?).
PostgreSQL 9.5 does not yet have the full code required for Bi-Directional replication. How did you hear that? Was that word of mouth, or is that written down anywhere so we can correct it?
I wants to play with multi-master, asynchronous replication on two servers PostgreSQL 9.5 beta 2.
Later versions of BDR will be compatible with later versions of PostgreSQL, until the features are fully merged. The full project has taken 4 years so far and we expect it to take another 2 years at least.
I'll write a blog about this because there is clearly some confusion around this.
In official docs very small information about how to configure servers.
Could anyone direct me in right way?
If anyone would like to contribute better documentation, they are very welcome to do so.
