I have spoken to users who are waiting for this feature to run in
production, which is why I suggested it.

Some people care more about correctness than they do about loss of performance.

Obviously, this would be expensive and those with a super high
performance requirement may not be able to take advantage of this. I'm
sure many people will turn it off once if they hit a performance
issue, but running it in production for the first few months will give
people a very safe feeling.

I think the primary use for an rmgr filter might well be PostgreSQL developers.
