Hello, Melanie! Sorry to interrupt you, just a quick question.

Do you have any patches\threads related to that refactoring (opportunistic freezing of tuples during pruning) [0]? This may affect the idea of the current thread (latest version of it mostly in [1]) - it may be required to disable such a feature for particular relation temporary or affect horizon used for pruning (without holding xmin). Just no sure - is it reasonable to start coding right now, or wait for some prune-freeze-related patch first?
