Actually, the reason proconfig is handled differently is that it's
a variable-length field, so it can't be represented in the C struct
that we overlay onto the catalog tuple to access the fixed-width
fields cheaply. I'm not sure that insisting that that stanza be
last is especially useful advice for future hackers, because someday
there might be more than one variable-length field that this function
needs to update.
