It's new in Postgres 7.4 I think you could do this in 7.3 though, it would just be more awkward. Try || but I think that's new in 7.4 as well. Otherwise I think you would have to pick out the upper bound of the array with array_dims and set the upper+1'th element of the array. If you're doing text you may want to go directly to a textual concatenation like: CREATE FUNCTION concat_agg_accum(text, text) RETURNS text AS 'select $1 || '', '' || $2' LANGUAGE sql IMMUTABLE STRICT; CREATE AGGREGATE concat_agg ( BASETYPE = text, SFUNC = concat_agg_accum, STYPE = text ); -- greg ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
