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))
