Always match the driver to your PostgreSQL server version, though newer drivers generally work with older servers (but not vice versa). The PostgreSQL ODBC driver (psqlODBC) is a mature, reliable solution for connecting diverse applications to PostgreSQL databases. Whether you're building reports in Excel, dashboards in Power BI, or custom applications in .NET or Python, the driver provides the necessary compatibility and performance features.
