docs: Improve the description of num_timed column in pg_stat_checkpointer.
The previous documentation stated that num_timed reflects the number ofscheduled checkpoints performed. However, checkpoints may be skippedif the server has been idle, and num_timed counts both skipped and completedcheckpoints. This commit clarifies the description to make it clear thatthe counter includes both skipped and completed checkpoints.Back-patch to v17 where pg_stat_checkpointer was added.Author: Fujii MasaoReviewed-by: Alexander KorotkovDiscussion:https://postgr.es/m/9ea77f40-818d-4841-9dee-158ac8f6e690@oss.nttdata.com
