We are pleased to announce the release of version 6.0 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 6.0 adds the ability to work with range types.
Users of Ubuntu and Fedora can install the extension directly from the rpm and apt repositories.
Please note that these is a bug in the GHC libraries in Fedora 44. If you are using Fedora 44, see the workaround.
If you have problems with the extension or a feature request, please submit a Github issue.
