See the Manfiold-Help: To work with PostgreSQL data sources we must have all PostgreSQL client DLLs (for example, LIBPQ.DLL plus any DLLs it depends on) to be installed in a folder referenced in the user's or system's PATH variable. The easiest way to be sure this is done is include the folder containing all PostgreSQL client DLLs in the system PATH variable. And this thread could be useful for you: Why you do a connection with OLE? If you have the Enterprise Edition take the native Postgres-Driver (PostgreSQL Data Sources() ). For an OLE-Connection, take as Provider your Postgres OLE-Driver, Port (default) should be 5432, the Server (default) should be: localhost Default-User name (postgres), Password: by installing the Postgres-DB at the point 'Initialize database cluster' you have tipped a password in But in your case with a connection over the network the default settings could be false, you must ask this one who administrate the Postgres-DB.
