Superfluous churn in the code isn't too bad. But superfluous churn in Data formats might be a bit scarier. Would we be able to handle pg_upgrade from a database with or without a freeze map? Would you have? To upgrade once to add the freeze map then again to remove it? Surely we wouldn't introduce and remove freeze-maps between minor versions. So either it is a new major version, in which case you would be doing the upgrade anyway, or they would be added and then removed again all within one development cycle; and running unreleased code always has on-disk incompatibility churn. Or am I missing your point here? Cheers, Martin ----- Kamagra -- Sent from: http://www.postgresql-archive.org/PostgreSQL-hackers-f1928748.html
