PostgreSQL Native Provider (PGNP) is an OLEDB Provider for PostgreSQL database.
The provider is a thin layer between Microsoft ADO and PostgreSQL API exposed via libpq library. It implements most of the OLEDB interfaces and uses libpq to access a PostgreSQL database.
The provider can be used from 32-bit and 64-bit applications both native and .NET. Its flexible architecture allows emulation of various databases SQL flavors (Enterprise edition) and saves customer from rewriting applications that originally developed for other databases.
Using DTS/SSIS wizards and included index conversion tools you can finally convert your SQL Server, Oracle, MySQL, or any OLEDB enabled database to enjoy the full power of PostgreSQL on Windows platform.
