Users sometimes get concerned whe they start the server and it emits a few messages and then doesn't emit any more messages for a long time. Generally, what's happening is either that the system is taking a long time to apply WAL, or it's taking a long time to reset unlogged relations, or it's taking a long time to fsync the data directory, but it's not easy to tell which is the case. To fix that, add a new 'log_startup_progress_interval' setting, by default 10s. When an operation that is known to be potentially long-running takes more than this amount of time, we'll log a status update each time this interval elapses. To avoid undesirable log chatter, don't log anything about WAL replay when in standby mode.
