I had to revert this on 9.5 and 9.6 -- it is obvious (in hindsight) that
changing StringInfoData is an ABI break, so we can't do it in back
The patch still remains in master, with the bugs you pointed out. I
suppose if somebody is desperate about getting data out from a table
with large tuples, they'd need to use pg10's pg_dump for it.
We could use the highest-order bit in StringInfoData->maxlen to
represent the boolean flag instead, if we really cared. But I'm not
going to sweat over it ...
