<para>
Specifies the minimum frequency, in seconds, for the WAL receiver
process on the standby to send information about replication progress
to the primary, where they can be seen using the
<literal>pg_stat_replication</literal> view. The standby will report
the last transaction log position it has written, the last position it
has flushed to disk, and the last position it has applied. Updates are
sent each time the write or flush positions changed, or at least as
often as specified by this parameter. Thus, the apply position may
lag slightly behind the true position. Setting this parameter to zero
disables status updates completely. This parameter can only be set in
the <filename>postgresql.conf</> file or on the server command line.
The default value is 10 seconds.
