The folks over at Geeklog have announced that their blogging application now supports PostgreSQL. Geeklog's move is similar to other open source projects that have recently diversified their support for more additional database management systems.
Dear Geeklog users, today we are proud to announce the public availability of Geeklog with beta PostgreSQL support. This is the culmination of a Google Summer of Code project to implement this feature. PostgreSQL support builds on the already impressive list of MySQL and MSSQL support. This continues to improve Geeklog’s interoperability, which now offers support for the most popular relational database management systems.
Support for Postgres currently is in beta and "should strictly be used on local and testing environments". Geeklog also supports MySQL and and MSSQL.
