Subject: Make pg_stat_wal_receiver consistent with the WAL receiver's shmem

d140f2f3 has renamed receivedUpto to flushedUpto, and has added
writtenUpto to the WAL receiver's shared memory information, but
pg_stat_wal_receiver was not consistent with that.  This commit renames
received_lsn to flushed_lsn, and adds a new column called written_lsn.

Bump catalog version.
