You have a problem :-(

The SQL spec is absolutely clear that the above code is wrong. What the
spec actually says is that unquoted names should be forced to all upper
case (so Table is equivalent to "TABLE"). Postgres forces them to lower
case (so Table is equivalent to "table") which is not quite the same but
has the same effect that unquoted names are not case sensitive. But
under both the exact spec rules and our rules, a mixed-case quoted name
is never equivalent to any unquoted name. There is no such thing as
case insensitivity for quoted names.
