Well, it's a SQL-compliance bug, and we often back-patch bug fixes.
The argument for not back-patching a bug fix usually boils down to
fear of breaking existing applications, but it's hard to see how
removal of a permission check could break a working application ---
especially when the permission check is as hard to trigger as this one.
How many table owners ever revoke their own REFERENCES permission?
