It looks like you need an aggregate function... but aggregate would work in case, you want to return a RECORD and not a SETOF RECORD. In this case, you probably need to operate with arrays. Are you on 8.3? If yes, you would be able to pass an array of type to your function. You can accumulate your type-array with array_accum(anyelement) aggregate (http://www.postgresql.org/docs/8.3/static/xaggr.html)... but I am not sure about the memory consumption in case of large arrays being passed to the function. If you are in the 8.2, you can still convert any type to text, and deconvert in the function: textin(point_out('(1,1)'::point)) With best regards, -- Valentine On Apr 28, 11:52 pm, rosen...@xxxxxxxxxxxxxxxxxxxxxxx (Viktor Rosenfeld) wrote: > Hi Jon, > > Am 28.04.2008 um 19:23 schrieb Roberts, Jon: > > >> What does the signature of graphovertokens look like?
