Hm. I guess that'd make sense. It's not really related to the goal of
making it realistic to test multixact/clog truncation, but it's less
confusing if consistent.

I seached for references and was surprised we don't document the limits
anywhere....

Seems to have been "broken" back in 834a6da4f7 - the old table based
approach doesn't seem to have imposed lower limits. I'm not really sure
whether making the limits consistent and updating the docs or removing
them alltogether is the better approach.
