Well, the above isn't legal plpgsql really (you'd need to be using
two quotes around NONE and there's a missing begin/end, I assume
you're just not showing those).

:)  Actually i didn't feel the need to write whole function. This function worked fine until there came a record with one empty field, and it returned me nothing.I feel the need to replace the Null fields with 'NONE' value...so that concatenated string should return me record. (It returns nothing if there is a field with no value inside it ..I mean empty field.)
