I created a user-defined type in a PostgreSQL 9.2 database and am trying in the `SELECT` statement to get only an attribute of the UDT. However, I don't seem to get my code to work.

Creation of type and table:

    CREATE TYPE  ttp AS (f1 int, f2 int);
    CREATE TABLE tbl (ctyp ttp);

The `SELECT` statement:

    -- does not work
    SELECT ctyp.f1 FROM tbl
    SELECT ctyp(f1) FROM testtable

Both times I get an error. Is it possible to access a single attribute defined in a UDT in a `SELECT`?
