Reassuringly all checks pass with a hack like that in place. (attached)
I think the right approach here is to define a new type text_packed * (which
would just be a char* or varattrib_1b* or something like that). Then
PG_GETARG_*_PP would return one of these new pointers.
This does leave us with warnings whenever an old-style function calls a
new-style function but I think there would be relatively few of those since
we'll tackle the higher traffic areas first which will be the lower level
functions.
The benefit is that it will give us a warning if we try to pass a pointer from
a new-style function to an old-style function which isn't prepared to receive
it.
