Equivalent of a RECORD[] data type used in a function? - Mailing list pgsql-general

Is it possible to have a function variable hold a recordset? Kind of
like this...

DECLARE
  recordset_var RECORD[];
BEGIN
  recordset_var := (SELECT id FROM myTable);
  /*
  loop through a ton of different tables where column IN
(recordset_var)
  */
END;

Thanks for any help! -Nick
