The only reasonable answer for this (a provably used, non-security, non-standards violating, non-gross functionality breakage case) is *zero*. Our historically cavalier attitude towards compatibility breakage has been an immense disservice to our users and encourages very bad upgrade habits and is, IMNSHO, embarrassing. Changing the way array_dims works for a minor functionality enhancement is gratuitous and should be done, if at all, via a loudly advertised deprecation/replacement cycle with a guarding GUC (yes, I hate them too, but not nearly as much as the expense of qualifying vast code bases against random compatibility breakages every release). merlin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
