This project is a "procedural language" extension of PostgreSQL allowing the execution of code in Haskell within SQL code. Despite the name, Haskell is, of course, not a procedural language as it is a functional language. However, "procedural language" is the term that PostgreSQL uses to describe languages that can be embedded in its SQL code.
The extension allows users, even unprivileged ones, to write, install, and run functions written in Haskell.
