Uh, thanks. I've just recognized I didn't know the meaning of "nuisance." I've looked up the meaning in the dictionary. Nuisance is like a trouble maker... Why do you think that it's better for VACUUM command to have the option? I think it's a table property whose value is determined based on the application workload, not per VACUUM execution. Rather, I think GUC is more useful to determine the behavior of the entire database and/or application. If we want to change a given execution of VACUUM, then we can ALTER TABLE SET, VACUUM, and ALTER TABLE SET back. Regards Takayuki Tsunakawa
