This commit updates the documentation for the pg_stat_checkpointer view to clarify what kind of checkpoints or restartpoints each counter tracks. This makes it easier to understand the meaning of each counter. Previously, the num_requested description included "backend," which could be misleading since requests come from other sources as well. This commit also removes "backend" from the description of num_requested, to avoid confusion. Author: Fujii Masao Reviewed-by: Anton A.
