Maybe I'm confused, but I don't think any of the proposals would require
you to do any of those things. The only case that requires any
significant new effort from the client app is where it reformats queries
before sending them on to the parser ... but that is knowledge you've
already built into the client, no? You just have to remember what you
did so that you can map a backend error index into the original text.
