You were clear, it's too early in the morning here.
You seem to be assuming that the files were changed close to the time you found the problem; as far as I can tell
that'snot actually true, they could have been changed back at the time of the file timestamps, and could have been
out-of-syncfor a while, right?
My suggestion to use pg_start_backup is irrelevant to the exact problem you're describing. The documentation for it
doesdescribe a good way to get a file-based backup, without stopping the server, and you might want to check into that.
Youcould also look at pg_base_backup.
