log_startup_progress_interval

doc html

<p>
         Sets the amount of time after which the startup process will log
         a message about a long-running operation that is still in progress,
         as well as the interval between further progress messages for that
         operation. The default is 10 seconds. A setting of <code class="literal">0</code>
         disables the feature.  If this value is specified without units,
         it is taken as milliseconds.  This setting is applied separately to
         each operation.
         This parameter can only be set in the <code class="filename">postgresql.conf</code>
         file or on the server command line.
        </p><p>
         For example, if syncing the data directory takes 25 seconds and
         thereafter resetting unlogged relations takes 8 seconds, and if this
         setting has the default value of 10 seconds, then a messages will be
         logged for syncing the data directory after it has been in progress
         for 10 seconds and again after it has been in progress for 20 seconds,
         but nothing will be logged for resetting unlogged relations.
        </p>
