## AI overview

The article describes the integration of extensions into PostgreSQL 9.1. It reports that the core patch work was largely committed and enhanced, that contrib modules were converted to extensions, and that upgrade scripts would support moving objects from an unpackaged state.

## Source excerpt

If you've not been following closely you might have missed out on extensions integration. Well, Tom spent some time on the patches I've been preparing for the last 4 months. And not only did he commit most of the work but he also enhanced some parts of the code (better factoring) and basically finished it. At the previous developer meeting his advice was to avoid putting too much into the very first version of the patch for it to stand its chances of being integrated, and while in the review process more than one major PostgreSQL contributor expressed worries about the size of the patch and the number of features proposed. Which is the usual process.
