You can't a record variable can only hold a single row.

FYI SELECT INTO in plpgsql is not the same as the SQL SELECT INTO:

http://www.postgresql.org/docs/9.2/interactive/plpgsql-statements.html#PLPGSQL-STATEMENTS-SQL-ONEROW

Tip: Note that this interpretation of SELECT with INTO is quite
different from PostgreSQL's regular SELECT INTO command, wherein the
INTO target is a newly created table. If you want to create a table from
a SELECT result inside a PL/pgSQL function, use the syntax CREATE TABLE
... AS SELECT.

One way I have gotten around this to create a temporary table in the
function and fill it with data and then select from it as suggested above.
