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