PostgreSQL is becoming a more popular choice for an embedded database because of its BSD license, relatively low memory footprint and great list of features. A few people have asked me if Slony would be a good choice for replication in an embedded environment. Embedded deployments haven’t been a primary use-case for Slony and some of the challenges you would face are worth writing about.



My talk on PostGIS replication at FOSS4G 2011 went well. It looked like there were about 150 people in the room. Most of them had not yet deployed a PostGIS replication solution.

My talk covered Slony and streaming replication. It gave an overview of different replication patterns that can crop on in the GIS space. I then gave an overview of the key features and limitation of Slony and streaming replication.

A video of the talk is available at FOSSLC
