Bhis commit introduces enhancements to the pg_stat_checkpointer view by adding three new columns: restartpoints_timed, restartpoints_req, and restartpoints_done. These additions aim to improve the visibility and monitoring of restartpoint processes on replicas. Previously, it was challenging to differentiate between successful and failed restartpoint requests. This limitation arises because restartpoints on replicas are dependent on checkpoint records from the primary, and cannot occur more frequently than these checkpoints. The new columns allow for clear distinction and tracking of restartpoint requests, their triggers, and successful completions. This enhancement aids database administrators and developers in better understanding and diagnosing issues related to restartpoint behavior, particularly in scenarios where restartpoint requests may fail. System catalog is changed. Catversion is bumped. Discussion: https://postgr.es/m/99b2ccd1-a77a-962a-0837-191cdf56c2b9%40inbox.ru Author: Anton A.
