What does that mean? An example of a query that is not covered by your current refactoring and still needs this check?
Yes. I added this comment: ... By the way, fixing this particular restriction grammatically might need huge refactoring in table_ref and friends. We'll see later, if it's really feasible.
Hmm, if I'm not mistaken, this if() was removed in branch. Does it mean I have done this huge refactoring, or I've removed it incorrectly and introduced a bug? Regards, Sergei Chief Architect MariaDB and security@mariadb.org
