We are pleased to announce the release of version 5.0 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 5.0 adds the ability to work with date/time types and advisory locking.

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.
