Multi-master replication

Hello All!

As I heard, PostgreSQL 9.5 has built in Bi-Direction replication (or need
install BDR module?).

Huh -- that may be so. But if it is, it contradicts the BDR
documentation: http://bdr-project.org/docs/stable/install-requirements.html

Maybe Andres might know the answer?

I wants to play with multi-master, asynchronous replication on two servers
PostgreSQL 9.5 beta 2.

In official docs very small information about how to configure servers.

Could anyone direct me in right way?

Have you looked here?

Thank you Merlin,

I see this doc too. But I confused, in 9.5 BDR placed to native code and
becomes built in feature.

So, need I install external BDR or try to config built in version ?

Or I didn't understood clearly.

BR, Dmitry

Hi,

I have understood that at 9.5 BDR is not implemented yet , but you have to download and install it from 2ndQuadrant , ie , a modified version of postgresql

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?

BDR does exist as production quality software.
http://bdr-project.org/docs/stable/index.html
BDR 0.93 is compatible with PostgreSQL 9.4.
Binary versions are available.

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.

If anyone would like to contribute better documentation, they are very
welcome to do so.
