> it is an educational tool so one would expect one to read the getting started pages first
This is the opposite of how it should be. You'd expect learners to be less likely to read a "getting started" page than an expert.
For example, saying to a beginner, "Oh, the tables are all prefixed with cd.tablename" will likely result in a look of confusion because the beginner didn't understand any of the words you used or the way in which you combined them. Is that period special, for example? You said prefix, so if I type "cd.tablenamefacilities" will that work? What are tables and how do I know what their "name" is? Why is the error message talking about "relations?" And so on.
