That's because explain.log_analyze requires executor instruments,
and it's not free. I think we'd better to have an option to avoid
the overheads... Oops, I found my bug when force_instrument is
turned on. It should be enabled only when
(explain_log_min_duration >= 0 && explain_log_analyze).
I send a new patch to fix it. A documentation about
explain.log_nested_statements is also added to the sgml file.
