Maybe, but note that that's fundamentally something that can become
stale immediately. And, just because an MVCC snapshot cannot see a row
does not mean that it cannot affect its transaction/statement in some
other way (e.g. unique index enforcement).

Again, you'll probably need to put this low level requirement into
context if you want sound advice from this list.
