Well, it's not only a matter of "are we going to clobber live state", it's also "is the state that we are looking at changing under us?". The -n switch only covers the first point. I think it would require some careful analysis, and testing that's never been done, before having any confidence in the results of pg_resetxlog on a live server. Why should you need this anyway? pg_migrator should not be having to run pg_resetxlog on the old installation, I would think. regards, tom lane
