Is there a page on the Wiki along the lines of "things that we would like to change if ever there is a substantial change in on-disk format that will break pg_upgrade"? ISTM that we should be intelligently saving those some place, just as Redhat presumably save up ABI-breakage over many years for the next major release of RHEL. Alexander's complaint is a good example of such a change, IMV. Isn't it more or less expected that the day will come when we'll make a clean break? -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
