I'm trying to connect DDA with Google Data Studio using the Postgres connector, anyone already did it who can help me how to do it?
I think I cannot do it because IP restrictions, but I'm not sure.
You are probably correct in the IP restrictions. Although I haven't used Google Data Studio, the help for the PostgreSQL connector in the notes list 12 IP address that you need to open access to the database.
