set up a postgesql database an have an existing file geodb. Imported/Exported features and tables from file geodb to postgresql database. Now in ArcGIS Desktop 10.4.1, I just want to add some fields and then calculate fields. I cannot get ArcGIS desktop to create the field. (just text fields). Is this a privilege setting in ArcCatalog to the specific feature or is this privileges on the postgresql database side?
