(ANALYZE, TIMING off)</> output, rather than just <command>EXPLAIN (ANALYZE)</>
153+
output. The overhead of repeatedly reading the system clock can slow down the
154+
query significantly on some systems, so it may be useful to set this
155+
parameter to <literal>FALSE</literal> when only actual row counts, and not
156+
exact times, are needed.
157+
This parameter is only effective when <varname>auto_explain.log_analyze</varname>
158+
is also enabled. It defaults to <literal>TRUE</literal>.
