I think the larger risk is breaking applications if we leave it this way. One such broken application is the format_type function and thus pg_dump. That can be fixed of course, but there might be more programs that use a similar simple-minded mechanism to check whether quoting is needed. Also, an empty identifier might be more likely to be a client program bug than really intended, especially in languages that handle variables loosely. OTOH, I'd suggest that we do not enforce the 128 maximum length mandated by SQL. :-) -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/
