Michael Paquier 96f052613f Introduce pg_stat_checkpointer ... Historically, the statistics of the checkpointer have been always part of pg_stat_bgwriter. This commit removes a few columns from pg_stat_bgwriter, and introduces pg_stat_checkpointer with equivalent, renamed columns (plus a new one for the reset timestamp): - checkpoints_timed -> num_timed - checkpoints_req -> num_requested - checkpoint_write_time -> write_time - checkpoint_sync_time -> sync_time - buffers_checkpoint -> buffers_written The fields of PgStat_CheckpointerStats and its SQL functions are renamed to match with the new field names, for consistency. Note that background writer and checkpointer have been split into two different processes in commits 806a2aee37 and bf405ba8e4. The pgstat structures were already split, making this change straight-forward. Bump catalog version.
