The proposed patch would result in a warning about every collation- sensitive index during every macOS major version upgrade, ie about once a year for most people. Seeing that Apple only actually touch their POSIX collations once a decade or so, that's way too far over on the crying-wolf end of the scale for me. We need something that has at least *some* connection to actual changes. regards, tom lane
