PostgreSQL is “the world’s most advanced open-source relational database”. It’s made by PostgreSQL Global Development Group.

Unfortunately, PostgreSQL like some open source projects such as  Maria DB  does not offer a ready to use ADO.NET provider.

Once the binaries are obtained it is possible to install a third party provider with the tool : “ProviderInstaller.exe”.

To be detected by PcVue, each ADO.NET provider must be installed in the Global Assembly Cache (GAC) of the .NET framework and referenced in the machine.config file. The tool “ProviderInstaller.exe” is there to facilitate this task.
