Speaking of which -- I think we could easily remove checkpoint_warning without any loss of useful functionality. Or, if we have to keep it, we could change the way it works: when that condition triggers, then cause regular "checkpoint started/complete" messages to occur (if they are disabled), rather than the current "checkpoints are occurring too frequently" message. -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/ "E pur si muove" (Galileo Galilei)
