So, do I > need to do a new 'initdb..' operation on machine M2 + restore from M1 > backups? Or is there another way to fix this? It sounds like you did not include pg_xlog in your rsync. What you have done is basically a cold backup. Cold backups must include pg_xlog, at least if you want them to work without WAL archival. If you look farther up in the log, it should tell you what xlog file it needs, and you can copy that from M1 if it is still there.
