suggestion for error statements

This is my first time posting and I' hope I'm posting in the correct place. I hope this is not an old topic I'm bringing to light...

It would be nice if when getting an error like: ERROR: Bad boolean external representation ''

(or the like)...it would give a column name where that error was found... I have to debug another programmers code and it would save me a lot of time if I quickly locate where that problem is occuring...

We have some wide tables.

Thanks...
