Unfortunatly - no. At least 8.1.6 says very bad words about this... :-(((
Also there is only MINUS in SQL reference SELECT grammar.
I tried to execute SQL worked on PostgreSQL, and was forced to do 2
corrections:
1. Replace EXCEPT with MINUS
2. Remove AS after subquery for target column
Both if I am not mistaken is ANSI/SQL. :-((
