Thanks for the advice. I’ve worked out how to get at the same information you showed (it’s available as PG::Result#error_field()). At this point, I just want to show that it is in principle possible to handle PG validations elegantly, so I can write this up and move on to the next thing. The obvious thing to cover next I think is stored procedures. I think I will cover writing them in PgSQL and ECMAScript. Is there anything I should cover that your average web developer might not know about this that they should? Debugging stored procedures is one thing that comes to mind; I’ll take advice on that or anything else anyone thinks I should share.
