EnterpriseDB provide a special purpose version of the
PostgreSQL open source relational database, targeted at Oracle compatibility.
Announced at LinuxWorld Conference and Expo, August 9, 2005, EnterpriseDB will provide sponsorship for further PostgreSQL development and release leadership, in addition to providing existing source code.
This is an excellent boost to PostgreSQL, already one of the best relational database management systems in the world as well as the most ANSI compliant.
Pumptheory.com uses and recommends PostgreSQL to it's clients and would like to welcome these investments by EnterpriseDB into the PostgreSQL community.
(Thank's to Solution Grove for alerting me to this press release.)
PostgreSQL began as Ingres in 1977 - you can read a short history of it's development here.
