Andres, I was talking this over with Jeff on the plane, and we wanted to be clear on your goals here: are you looking to eliminate the *write* cost of freezing, or just the *read* cost of re-reading already frozen pages?
If just the latter, what about just adding a bit to the visibility map to indicate that the page is frozen? That seems simpler than what you're proposing. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
