-- ROWTYPES
--
-- Make both a standalone composite type and a table rowtype
create type complex as (r float8, i float8);
create temp table fullname (first text, last text);
-- Nested composite
create type quad as (c1 complex, c2 complex);
-- Some simple tests of I/O conversions and row construction
