I don't think so using string_agg is good name (- as minimal (and only one) reason is different API - there is no support for delimiter. If I remember well discussion about string_agg, where delimiter is not optimal, there is request for immutable interface for aggregates - there was a issue with ORDER clause. So bytea_agg is good name. Regards Pavel >
