Subject: SELECTing into usertype, how to do it?

I have a type, declared like this:
CREATE TYPE type_a AS (
member_a varchar,
member_b bool
);
There is also a table:
CREATE TABLE table_a (
col_a varchar,
col_b bool,
col_c int4
);
Now, in a function, I declared type_var variable of type type_a:
DECLARE type_var type_a;
And then, when I want to fill in the type_var, i do this:
type_var.member_a := col_a FROM table_a WHERE col_c = 5;
type_var.member_b := col_b FROM table_a WHERE col_c = 5;
Is there a way to fill in the type_var, but from just one statement?
Here I have two 'selects' on table_a, and that seems as bit expensive
when iterated a lot of times.
I guess I could do:
SELECT col_a, col_b INTO type_var.member_a, type_var.member_b FROM
table_A WHERE col_c = 5;
but that is a bit hard to read :)
Are there more options on doing what I'd like to do?
Mario
