PostgreSQL 8.3 has been released. This new version introduces a number of functionalities and big performance improvements. Some of the new additions include full text searching integrated into core, support for SQL/XML standard, enumerated types and arrays of composite types. Performance improvements include an important reduction on data files size, improved performance in UPDATEs and DELETEs (HOT) among others.

At NaN, we are happy to have been able to make a couple of small contributions in this new version, on one side by incorporating the documentation of contrib modules into main PostgreSQL documentation, letting those modules to be known to many users that didn't know of their existance. On the other, starting the development of a small performance improvement when using temporary tables and sorting files.
