The practical applications of the 64-bit driver are vast. In processes, SQL Server Integration Services (SSIS) running on a 64-bit server uses the driver to pull millions of rows from PostgreSQL into a data warehouse. In geospatial analysis , QGIS or ArcGIS Pro (both 64-bit) connect via ODBC to a PostGIS database to render maps from spatial data. In financial modeling , a 64-bit Excel workbook with Power Query can directly query a PostgreSQL database for real-time risk calculations, bypassing manual CSV exports. Even in software development , legacy applications written in Delphi or C++ can be modernized to talk to PostgreSQL without rewriting their database access layers, simply by switching the ODBC DSN. postgresql odbc driver 64 bit
