We are pleased to announce the release of version 2.0 of the PL/Haskell extension. This extension allows users to write PostgreSQL functions in the Haskell functional programming language. Instructions can be found here.
Version 2.0 adds the ability to execute queries from within PL/Haskell functions. In addition, the build and install procedures have been made simpler and more robust.
Users of Ubuntu and Fedora can install the extension directly from the rpm and apt repositories.
If you have problems with the extension or a feature request, please submit a Github issue.
