The idea looks interesting to me. But, as Euler Taveira mentioned,
can't we extend an existing function pg_stat_statements_reset()
instead of adding a new one and update the documentation for it. Also,
in the test-case it would be good to display the output of
pg_stat_statements before and after deleting the query. Thanks.
