Is there any way to covert an instance of a composite type to text,
to store it in a text column, and then to recreate the original object?
For example:
create type test as (a integer, b text);
create tble tstore (s text);
insert into tstore values((someproc((row(1, 'tst'))::test))::text);
select (someproc(s))::test from tstore;
BTW, I succeeded to create an array of composite types althought I think
i met somewhere in the docs that these are still not supported.
I did it by fiddling with the system catalogs.
