Ouch, that's pretty old (and not even the latest of the 7.1 series).

Can you find any pg_class rows with OIDs matching those file names?
I don't think that 7.1 would ever change relfilenode on ordinary
tables, but it does do so for indexes if you REINDEX.
Also, how large is pg_log ($PGDATA/global/1269)? I'm wondering about
transaction ID wraparound, which was still an unsolved problem in 7.1.
