In PG Admin 4, I use the dashboard, server activity to explore sessions on PG v12.1.
In the Details panel of the session, I can see the start of the SQL, but when it's a long text query on multiple lines, How can I access the entire SQL command ?
In PGAdmin 3 (on oldest PG v9.4), in tool server state, I was using for that purpose, the button that launch the query editor for the selected session with the entire SQL command.
