Two attributes related to checkpointer statistics are removed in this commit: - buffers_backend, that counts the number of buffers written directly by a backend. - buffers_backend_fsync, that counts the number of times a backend had to do fsync() by its own. These are actually not checkpointer properties but backend properties. Also, pg_stat_io provides a more accurate and equivalent report of these numbers, by tracking all the I/O stats related to backends, including writes and fsyncs, so storing them in pg_stat_checkpointer was redundant. Thanks also to Robert Haas and Amit Kapila for their input. Bump catalog version.
