The Vita Voom Software™ pgExpress Driver born out of the lack of good PostgreSQL support for the Delphi community. Mr., , pgExpress Driver's author, have also worked on the Zeos Library project for a couple months, but quit from it since he couldn't agree with many of the development directives.
The pgExpress Driver was developed months earlier then Codegear's PostgreSQL Driver for Kylix, and at the time it was developed, it was the first driver in the world written using Delphi. We released the first pgExpress Driver beta in July 05, 2001.
Since then, Vita Voom Software™ have stablished itself as a leading PostgreSQL access provider for the Delphi community.
