This is the most frustrating experience I have ever had with software installation by a fair margin, but I really need to learn SQL and would like to use this tool. 

Is there any way to completely uninstall it, and start again, and get the permissions resolved? I have spent days asking chatbots to resolve this issue but their help was insufficient. Again, psql works fine, but I want to be able to follow along with a course taught with the actual tool. 

Thanks, 

Brian
