Re: add queryEnv to ExplainOneQuery_hook

Passing NULL in place of queryEnv in PG10 causes a failure in installcheck
tests portals and plpgsql.

For PG10, if you want a both an ExplainOneQuery hook and clean run of
installcheck, is there a better workaround than to (a) pass NULL in place of
queryEnv, and (b) to comment out the portals and plpgsql tests?
