<varname>auto_explain.log_timing</varname> causes <command>EXPLAIN
|

|
(ANALYZE, TIMING off)</> output, rather than just <command>EXPLAIN (ANALYZE)</>
|
||||||
|
output. The overhead of repeatedly reading the system clock can slow down the
|
||||||
|
query significantly on some systems, so it may be useful to set this
|
||||||
|
parameter to <literal>FALSE</literal> when only actual row counts, and not
|
||||||
|
exact times, are needed.
|
||||||
|
This parameter is only effective when <varname>auto_explain.log_analyze</varname>
|
||||||
|
is also enabled. It defaults to <literal>TRUE</literal>.
