Yeah, I would not be happy either with elog(LOG) suddenly getting
10x more verbose.  I think it might be okay to unconditionally do this
when elevel >= ERROR, though.

(At the same time, I don't have a problem with the idea of a GUC
controlling the minimum elevel to cause the report.  Other people
might have other use-cases than I do.)
