Variable assignment from dynamic SQL in PL/PgSQL

Kind people,

I've figured out something that many others probably have, but I
thought I'd put it out there anyhow.

As PL/PgSQL doesn't allow assignment of singleton SELECTs and dynamic
queries to variables, as mentioned in the docs.

Here's a working hack that gets around this.

DECLARE foo_rec RECORD;
BEGIN
FOR foo_rec IN EXECUTE -- put together a singleton sql function here.
LOOP
END LOOP;
-- do stuff with foo_rec.bar, foo_rec.baz, &c.
END;

Should this hack turn into a TODO item? If so, what problems should
get addressed? Features added? Is PL/PgSQL in such shape as it needs
a big overhaul?

Anyway, thanks for taking the time to read this.

Cheers,
D
