That's what diagnostics are for. (And Explain.)

But isn't it reasonable for the server to be able to detect meaningless
queries and avoid trying to execute them, and return a diagnostic?

But the database and record format are not necessarily independent. You can
name specific schemas for a given database.   So your point here, I assume,
is don't mix term records and real record in the same database. Ok that
makes sense.  So one database for the real records and a second database (or
however many you want) for the term records.
