17th September 2020: PostgreSQL 13 RC 1 Released!

walbouncer: partial transaction log replication

Posted on 2014-10-22 by CYBERTEC PostgreSQL International GmbH

We are proud to announce walbouncer 0.9 - a tool to filter transaction log. At this point we are moving rapidly closer to a production-ready tool.

The key advantage of walbouncer is that it is no longer necessary to replicate entire database instances. You can filter out entire databases and tablespaces and selectively choose what to replicate.

walbouncer can act as a WAL proxy distributing data flexible to various servers containing different subsets of data.

walbouncer is open source and can be downloaded freely from our website. Currently PostgreSQL 9.4 is supported.
