I appreciate the response @pfaffman. I can write the SQL, but working in a rails console is a little outside my wheelhouse. How can I get into the discourse python console 
?
Would be nice - though I understand also potentially dangerous - if there was a tool like the data explorer that also let you write an UPDATE query.
Anyone know if there is a way to connect a third party SQL tool (like Sequel Pro or equiv) to the running DB in self-hosted docker discourse?
