PostgreSQL: PL/Haskell v4.0 Released

[NewsBot]

A new PostgreSQL blog post/announcement has been posted!

We are pleased to announce the release of version 4.0 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 4.0 adds the ability to work with arrays.

This release adds the ability to pass composite values to queries.

Note that there is a break of backwards comparability regarding composite types returned from queries.

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.
