The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/14/xfunc-sql.html
Description:
On the page „ 38.5. Query Language (SQL) Functions“ below the example
CREATE FUNCTION new_emp() RETURNS emp AS $$
SELECT ROW('None', 1000.0, 25, '(2,2)')::emp;
$$ LANGUAGE SQL;
this sentence is wrong:
„ Here we wrote a SELECT that returns just a single column of the correct
composite type.“
It is not a single column but a single row that is returned.

It's also a single column, which is more relevant to the point being
made. Compare this to the immediately preceding example.
