It's great to see that you people care about "userland", judging by the
effort that you describe in your article.
In fact you're already doing the thing that i asked about, i see that even
the offending tuple is printed (which is new).
And of course it's not necessary to mention the column name when you
mention the constraint name.
(BTW: your remark about NOT NULL constraints is not necessary, that error
message is very clear:"ERROR: null value in column "balance" violates
not-null constraint" )

This is not a constraint going off, and in this case, none of that applies.
But it seems probable to me that some day it will, seeing as you already
implemented it for constraints.
