If so, what if replication is terminated and restarted repeatedly while a restartpoint is running? It sometimes obeys and sometimes ignores checkpoint_segments. Which seems strange behavior. > Plus, adding SharedStartupStandbyMode into > XLogCtlData seems accompanied with some annoyances which would > not pay. Hmm... what are you worried about? I don't think that sharing the variable via XLogCtl is so difficult. Please see the code to share archiveCleanupCommand from the startup process to the checkpointer. It looks very simple. > By the way, do you have some advise about GetStandbyFlushRecPtr() > and the order of the locations? I'm embarrassed with that... Sorry. I could not parse this.... Could you explain this again?
