I went to two days of [OSCON](http://conferences.oreillynet.com/os2005/) last week. My company finally decided to send me on Monday. The first day, August 2, I went to the Slony-I Replication Tutorial. [Slony](http://slony.info) is a replication system for [PostgreSQL](http://www.postgresql.org). We use it at work to replicate a master database to two slave databases. This is done so the slave databases can be used for generating reports and the master database just does importing.

Most of the material was stuff I had learned before. There were a few nuggets of information I hadn’t known before. And I got some of my important questions answered.

It was also nice to learn that other people are using Slony in large deployments like we are and that it performs well.
