I am using the psqlODBC driver to connect to Amazon RDS. I am able to connect successfully after enabling SSL encryption via the connection string parameter "sslmode=require". I want to now enable verification of server identity too, which means that I need to provide the CA certificate path to the Postgres driver. I tried the connection parameters "sslmode=verify-full;sslrootcert=<path to CA file>", but the driver is not able to pick up the file from the specified path (I tried on Windows and Mac OS X). Things work, however, when the certificate is placed in the default place the driver looks in - %APPDATA%\Roaming\postgresql\root.crt on Windows; ~/.postgresql/root.crt on Mac.
Is this a bug that needs to be fixed or am I doing something wrong? I am using psqlodbc version 09_03_0300-1.
