PhpPgAdmin
phpPgAdmin is a web application, written in PHP, for managing PostgreSQL databases.
phpPgAdmin is a web-based client which leverages PHP scripting and the PostgreSQL database to provide a convenient way for users to create databases, create tables, alter tables and query their own data using industry-standard SQL.
The project originally started as a fork of phpMyAdmin, to provide PostgreSQL users with comparable services to what MySQL users had been using. However, in 2002, the code was re-written from scratch, and is now a completely different code base.
