PostgreSQL donates Database Replication software [LWN.net]

PostgreSQL, Inc has announced that it has contributed version 1.0+ of its eRServer database replication software to the open-source community. [PostgreSQL]

Replication is one of the most critical utilities for enterprise databases, and this release makes that capability accessible to qualified developers and users who could not previously afford replication because of software licensing or support fees.

The company has a policy of relicensing its commercial software two years after its commercial release, eRServer has been made available one month ahead of that schedule. '*All* proprietary developments that we are involved in *will* become open source within two years of implementation, without exception."'

The eRServer software will be released under the BSD license.

The company's president, Marc Fournier warns of the possible difficulties involved with using the replication software, and suggests that users consider purchasing their commercial support. "replication can be an extremely complex area for programming in enterprise systems - so even the more advanced database users should expect to invest a good deal of development time and effort in properly deploying this software."

This will be a welcome addition to the arsenal of open-source database tools, the company should be commended for their actions.
