I need to query, create, update, delete records of postgres db table from sharepoint 2016 on premises (single server), preferably sharepoint list or if not possible then html form/table embedded in the sharepoint page. I'm looking for free solutions so layer2solutions is not an option. I tried to connect with connectionstring (Data Provider: MS .NET Fr for ODBC) from sharepoint designer 2013, but it didnt work. I have VS 2015 but no template for BDC (sharepoint). Now I check node.js if it could work. Do you have any ideas?
