Dear Bharath, Thanks for re-working the project.
While seeing the old discussion, I found that Robert Haas was agaist the XID-based invalidation, because it's difficult to determine the cutoff age [1]. Can you clarify your thought against the point? Are you focusing on solving the wraparound issues, not for bloated instance issue? The code may not be accepted unless we got his agreement.
