Free haskell postgresql software for linux

logindpostgres is a script that reads SQL select statements from PostgreSQL logs and generates all the indices to optimize the database for each request.

logindpostgres has been tested on 1.2 GB of logs.

RSA-Haskell is a collection of command-line cryptography tools and a cryptography library written in Haskell. The project is intended to be useful to anyone who wants to secure files or communications or who wants to incorporate cryptography in their Haskell application.
The libraries include Haskell implementations of SHA1, EME-OAEP, EMSA-PSS, MGF, RSAES-OAEP, and RSA-PSS. These standards implement signature/verification, strong cryptography, and hashing.
Enhancements:
- Documentation is now available for the command line utilities.
- An easy-to-use Windows binary release is available.

OpenLDAP-PostgreSQL Linux HOWTO is a HOWTO for implementing PostgreSQL as an SQL backend for OpenLDAP.

This HOWTO doesnt talk about OpenLDAP, PostgreSQL or iODBC in this document I suppose that you know all that, I just provide my personnal installation of these apps.

So in this new version I will try to give all installation and configuration requirement to have OpenLDAP running with a PostgreSQL backend and a complete live example to let you see how is the work that should be done on a medium directory.

This is what I have in production state in my company with a master Bekerley db backend replicated to a remote LDAP directory using PostgreSQL as backend.

LDAP for Haskell package contains a LDAP binding for Haskell. This package provides read and write support for LDAP directories.

Haskell is a standardized purely functional programming language with non-strict semantics, named after the logician Haskell Curry. It is one of the more popular functional languages, and the lazy functional language on which the most research is being performed.

Characteristic features of Haskell include pattern matching, currying, list comprehensions, guards, definable operators, and single assignment. The language also supports recursive functions and algebraic data types, as well as lazy evaluation. Unique concepts include monads, and type classes. The combination of such features can make functions which would be difficult to write in a procedural programming language almost trivial to implement in Haskell.

Several variants have been developed: parallelizable versions from MIT and Glasgow, both called Parallel Haskell; more parallel and distributed versions called Distributed Haskell (formerly Goffin) and Eden; a speculatively evaluating version called Eager Haskell and several object oriented versions: Haskell++, OHaskell and Mondrian.

There is also a Haskell-like language that offers a new method of support for GUI development called Concurrent Clean. Its biggest deviations from Haskell are use of uniqueness types for input instead of monads.

Proboscis is a pure Python driver/interface for PostgreSQL.

It is designed to give maximum flexibility to a user by providing protocol-level prepared statements and cursors.

It features basic SSL support, COPY TO/FROM, automatic encoding/decoding, and much more.

kpsql is a graphical front-end to psql, the PostgreSQL interactive terminal.

kpsql has been tested on 3.4.3 and 3.5, seems to work.

Installation:

1) extract to dir where you want it to be installed
2) run setup.bash to create a desktop icon

Npgsql is a .Net data provider for Postgresql. It allows any program developed for .Net framework to access database server.

Npgsql library is implemented in 100% C# code. Works with Postgresql 7.x and 8.x.
