Fair point, looks suspicious on first sight. I've checked my tests briefly: It's accepted as table and column name. As mentioned in footnote [0] I haven't checked different contextes yet.

Can you tell me: what kind of identifier is it (view name, function name) and which SQL context it causes problems (select list, create/drop statement, ...) and which system has problems with it. Thx.
