That's a good point.

In the case I referred to [1] however I wanted to manipulate more
fields than pg_resetwal currently allows, e.g. catalog version -
which, as Tom pointed out, is a controversial thing to do in a TAP
test.

Do you think pg_resetwall should be able to do more than it currently
does, or merely pointing out that we already have a tool for editing
pg_control file?
