The question is whether string_to_array is meant to be useful for lists of anything except text. I agree you could argue that it isn't. But even in the domain of text it's not all that cut-and-dried whether string_to_array should return array[] or array[''] for empty input. So ISTM we're giving up less than we gain by choosing the former. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
