OK, so it's not a simulation of the MySQL syntax - MySQL requires no hints.
I've looked thru the code and yeah, basically that's what you have to do, so
long as you can get the app programmer to tell you in the code what the
primary keys are. For a postgres implementation, it's more difficult.
BTW, there's no documentation anywhere in your code - makes it a bit
difficult to see what's going on...
