https://community.qlik.com/t5/Data-Quality/Cannot-connect-to-PostgreSQL-from-Open-Studio-for-Data-Quality/m-p/2274390#M2970 Hi, <BR />I'm trying to connect to a 9.4 PostgreSQL instance from&nbsp;Open Studio for Data Quality v6.1.1. I followed the steps to create a new DBConnection. I reached the point where I see a "Check" button for the connection. When I press the button I receive a popup asking for missing modules. <BR />In the popup the missing jar is "postgresql-9-4-1201.jdbc41.jar" and the module is blank. In the Action I see a jar icon if I press I get a file selection window. And the "Download and install all modules available" button is not enabled. <BR />The missing file is available in the following location <BR />/plugins/org.talend.libraries.jdbc.postgresql_6.1.1.20151214_1327/lib/postgresql-9.4-1201.jdbc41.jar <BR />Any idea how can I connect to PostgreSQL? <BR />Thanks.
