Improve documentation for pg_stat_checkpointer fields
pg_stat_checkpointer contains statistics for checkpoints and restartpoints. Before12915a58ee
documentation said only about checkpoints implying that restartpoint is the variation of checkpoint.12915a58ee
introduced new separate statistics fields for restartpoints. This commit explicitly documents fields that are relevant for both checkpoints and restartpoints.
