+ Query and Index Statistics Collector
+
+
+
+ STATS_START_COLLECTOR (boolean)
+
+
+ Controls whether the server should start the
+ statistics-collection subprocess. This is on by default, but
+ may be turned off if you know you have no interest in
+ collecting statistics. This option can only be set at server
+ start.
+
+
+
+
+
+ STATS_COMMAND_STRING (boolean)
+
+
+ Enables the collection of statistics on the currently
+ executing command of each session, along with the time at
+ which that command began execution. This option is off by
+ default. Note that even when enabled, this information is not
+ visible to all users, only to superusers and the user owning
+ the session being reported on; so it should not represent a
+ security risk. This data can be accessed via the
+ pg_stat_activity system view; refer
+ to for more information.
+
+
+
+
+
+ STATS_BLOCK_LEVEL (boolean)
+ STATS_ROW_LEVEL (boolean)
+
+
+ These enable the collection of block-level and row-level statistics
+ on database activity, respectively. These options are off by
+ default. This data can be accessed via the
+ pg_stat and
+ pg_statio family of system views;
+ refer to for more information.
+
+
+
+
+
+ STATS_RESET_ON_SERVER_START (boolean)
+
+
+ If on, collected statistics are zeroed out whenever the server
+ is restarted. If off, statistics are accumulated across server
+ restarts. The default is on. This option can only be set at
+ server start.
+
+
+
+
+
+ DEFAULT_STATISTICS_TARGET (integer)
+
+
+ Sets the default statistics target for table columns that have not
+ had a column-specific target set via ALTER TABLE SET
+ STATISTICS. Larger values increase the time needed to do
+ ANALYZE, but may improve the quality of the planner's
+ estimates. The default value is 10.
