Presumably they could also run a query that accidentally consumes all
the CPU and I/O bandwidth on your server (hello missing WHERE clause!)

It sounds like what you need is an intermediate layer that enforces
transaction and query timeouts, rather than giving your mech/eng types
direct access to the DB.
