Good you managed to solve your issues.
As to DBeaver: yes, it takes a little bit of time to get used to, however, once you have used it a bit longer, there is much to like about the application. I have also found the developer very responsive and pro-active regarding bug reporst reports and enhancement suggestions. At least it is a much better application than pgAdmin3. I haven't yet looked at pgAdmin4, so can't compare them yet.
As to coordinate read-out in DBeaver, simply switch to Data view and select the way column and a record, then choose "Copy" from the right-click context menu. You can subsequently paste in Notepad, as I did in this screenshot.
