This indicates that the LSN word of that block contains 2/13CEA8AC,
which is impossibly large if WAL currently extends only to 2/13634EE4.
Have you had any crashes or other odd behavior recently?
What files do you see in $PGDATA/pg_xlog/? Can you grab a copy of
pg_filedump and look at what the block contains on-disk?
