As part of the Citus team (Citus scales out Postgres horizontally, but that’s not all we work on), I've been working on pg_auto_failover for quite some time now and I'm excited that we have now introduced pg_auto_failover as Open Source, to give you automated failover and high availability!

When designing pg_auto_failover, our goal was this: to provide an easy to set up Business Continuity solution for Postgres that implements fault tolerance of any one node in the system. The documentation chapter about the pg_auto_failover architecture includes the following:

Today, we’re excited to announce that we have donated 1% of Citus Data’s stock to the non-profit PostgreSQL organizations in the US and Europe. The United States PostgreSQL Association (PgUS) has received this stock grant. PgUS will work with PostgreSQL Europe to support the growth, education, and future innovation of Postgres both in the US and Europe.

To our knowledge, this is the first time a company has donated 1% of its equity to support the mission of an open source foundation.

To coincide with this donation, we’re also joining the Pledge 1% movement, alongside well-known technology organizations such as Atlassian, Twilio, Box, and more.
