Hi,
I'm trying to programmatically connect to an RDS Postgres instance with SSL enabled, using the psqlodbc driver (Version: postgresql94-odbc-09.03.0400-1PGDG.rhel6.x86_64.rpm). I’m having trouble with the sslrootcert parameter.
To enable SSL for a Postgres connection, I appended the following parameters to the connection string:
sslmode=verify-ca;sslrootcert=<location of root certificate on the client>
The root certificate exists as a .pem file.
In addition, I also enabled the debug and comm logs:
debug=1;commlog=1
The resulting logs showed the following error:
…

Does this mean the driver cannot recognize the sslrootcert parameter being passed to it?
