Hmm ... Postgres wants it without the innermost parentheses:        (SELECT "grupp", "liik" FROM          "artliik")

Offhand though I am not certain whether the way you wrote it is supposed
to be allowed according to the SQL spec.  Does anyone think this should
have worked, and if so what's the chapter and verse that says so?
