I'd like to announce the release of version 1.0 of the PL/Haskell extension. This extension allows users to write PostgreSQL functions in the Haskell functional programming language. Code and build instructions can be found at:

Code can be downloaded at:

Currently, there is no ability to access the DB from inside of Haskell functions. However, if there is enough interest from the community, I may release a subsequent version with this ability.

If you have any questions or comments, send me an email ( If you have problems with the extension, submit a GitHub issue.
