TurnKey PostgreSQL Appliance is a server appliance for PostgreSQL, a fully-featured object-relational database with many enterprise features: ACID transactions, inheritance, Unicode, and strong support for the SQL-92 standard including subqueries, views, outer joins, foreign keys, sequences, and triggers. It is designed to be easy to use and easy to maintain. Security patches are automatically installed. It provides a Web management interface, configuration console, and an AJAX Web shell. To minimize footprint the appliance is built from the ground up with the minimum required components. It runs everywhere thanks to multiple build formats, including an installable live CD, a VMDK with OVF support, and an Amazon EC2 AMI.
