Thanks! Looking at the code, and documentation this seems a worthwhile
addition. Manual testing proves that it works as expected, and the patch
follows the expected style. A few small comments:
Since DEBUG is not a defined loglevel, it seems superfluous to include it here.
It’s also omitted from the documentation so it should probably be omitted from
here.
+ {"debug", DEBUG2, true},
The <varname> tag should be closed with a matching </varname>.
+ <primary><varname>auto_explain.log_level</> configuration parameter</primary>
With those fixed it’s ready for committer.

Agreeing that this would be beneficial, the attached patch (to apply on top of
the patch in question) takes a stab at adding tests for this new functionality.
In order to test plan output we need to support COSTS in the explain output, so
a new GUC auto_explain.log_costs is added. We also need to not print the
duration, so as a hack this patch omits the duration if auto_explain.log_timing
is set to off and auto_explain.log_analyze is set off. This is a hack and not
a nice overloading, but it seems overkill to add a separate GUC just to turn
off the duration, any better ideas on how support omitting the duration?
