       <varname>pg_stat_statements.track_planning</varname> controls whether
       planning operations and duration are tracked by the module.
       Enabling this parameter may incur a noticeable performance penalty,
-      especially when a fewer kinds of queries are executed on many
-      concurrent connections.
+      especially when statements with identical query structure are executed
+      by many concurrent connections which compete to update a small number of

       The default value is <literal>off</literal>.
       Only superusers can change this setting.
