Обсуждение: Casting 'record' to a composite type.

Hello,
When using functions that return the datatype 'record', rather than
doing this:

    SELECT *
    FROM fn_returning_setof_record( ... )
    AS t (id integer, title text);

I'd like to do something like this:

    CREATE TYPE my_type AS (id integer, title text);

    SELECT *
    FROM fn_returning_setof_record( ... )
    AS t my_type;
or
    SELECT *
    FROM fn_returning_setof_record( ... )::my_type AS t;

Obviously the last two statements don't work, but you can see what I'm
getting at,
casting the 'record' datatype to a composite datatype.
I've not been able to find anything like this in the docs.
Is there currently any way of doing this? are there any plans for it?

Cheers

There is no way to do this now, and no plans that I know of, but it does
look useful. I'm not sure how painful it would be to make it happen
though...
