I am currently porting the MySQL parts to PostgreSQL, hoping to maintain the rest of the API verbatim.
This library is a mid-level Haskell binding to PostgreSQL servers. It is aimed at speed and ease of use.
This library is BSD-licensed.
This library is written and maintained by Chris Done, chrisdone@gmail.com.
This library is also directly forked from mysql-simple, written and maintained by Bryan O'Sullivan, bos@mailrank.com, with the MySQL parts changed to PostgreSQL, in order to have a consistent API.
