Q: Why did I fail to create a PostgreSQL datasource in SuperMap iDesktop 8C?

A: You can refer to the user guide for PostgreSQL in the help document of SuperMap iDesktop 8C. Still, there are some supplementary points listed here for your reference. 1. Install PostgreSQL version 8.3 and higher versions. 2. Choose “C” as Runtime locale during the installation. 3. Modify the environment variable if the command for creating a PostgreSQL datasource is gray when the installation is complete. Find the Path environment variable through Start> Control Panel> System> Advanced System Settings> Environment Variables, and add the bin path of the PostgreSQL installation directory such as: C:\Program Files\PostgreSQL\9.0\bin to the Path environment variable. 4. The desktop software and PostgreSQL should be both either 32-bit or 64-bit.
