Frankly, I thought it was probably too late for 9.2 when it was first proposed, and the number of issues that have been identified since then just confirm that feeling. There is another point beyond the ones in your summary: if we squeeze checksums into the page header without increasing its size, however we do it there will be no going back, because we will certainly have used up all the remaining wiggle room there. That means we'll be absolutely committed to this implementation, permanently (or at least until we invent the page format upgrade code that no one seems to want to build). I think we need to be a lot more certain that we're happy with the design and can't improve on it before we make that commitment. What I'd like to see is for Simon to keep hacking on the identified issues, with the hope of having a solid patch ready to commit early in the 9.3 cycle. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
