I would be interested in seeing the structure of the index, if there is
anything else corrupt in there. Also, what WAL actions led to the error?
Try something like:
pg_xlogdump -r btree -p $PGDATA -s 339/65000000 | grep 1665279
and search that for any records related to the failed split, e.g.
grepping further for the block numbers in the error message.
