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 branches; see https://www.postgresql.org/message-id/27737.1480993...@sss.pgh.pa.us 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 ... -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
