This looks in pretty good shape to me, and no objections from me to get those functions as the min() flavor is useful for monitoring WAL retention for complex deployments. Do you have a particular use-case in mind for max() one? I can think of at least one case: monitoring the flush LSNs of a set of standbys to find out how much has been replayed at most. -- Michael
