TBH, it has never been more than the shakiest of assumptions that the new version could not create toast tables where the old one hadn't. I think you should just allow for that case, independently of specific PG versions. Fortunately it seems easy enough, since you certainly don't need to put any data into the new toast tables. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
