Sorry about the top-post.
Alexandre, did you ever use pg_resetxlog on that cluster?

This database used to be managed by someone else and we started managing it
recently. Our team didn't run pg_resetxlog for sure.
I just chatted with the previous team and it looks like it was never ran
either. This is a fairly old database and it's not its first upgrade.
