After the linux (DEB or RPM) driver is installed, a DSN with the name DEVART_POSTGRESQL is created. You can use it to test the connection with the POSTGRESQL server. For this, perform the following steps:
User ID=<your PostgreSQL User Name>
Password=<your PostgreSQL password>
Host=<your PostgreSQL Server Name>
Port=<your PostgreSQL Port>
Database=<your PostgreSQL database name>
isql -v DEVART_POSTGRESQL
