After thinking about this a while, I convinced myself to change the
column names to be a bit more meaningful. I still think having
checkpoints in the column names is needed because it also has other
backend related columns. I'm attaching the v4 patch for further
review.
CREATE VIEW pg_stat_checkpointer AS
SELECT
pg_stat_get_timed_checkpoints() AS timed_checkpoints,
pg_stat_get_requested_checkpoints() AS requested_checkpoints,
pg_stat_get_checkpoint_write_time() AS checkpoint_write_time,
pg_stat_get_checkpoint_sync_time() AS checkpoint_sync_time,
pg_stat_get_buf_written_checkpoints() AS buffers_written_checkpoints,
pg_stat_get_buf_written_backend() AS buffers_written_backend,
pg_stat_get_buf_fsync_backend() AS buffers_fsync_backend,
pg_stat_get_checkpointer_stat_reset_time() AS stats_reset;
