OK, I got it now -- good old pascal/FORTRAN fashion. But now I get
adressen=> CREATE INDEX xxx ON geburtstage (geb_monat(geburtstag));
ERROR: DefineIndex: (null) class not found
adressen=>
What is a class in this sense, and where can I read about it in the

(geburtstag is a row of type DATE in the table geburtstage)
