Is there any case that query_text will be NULL when executing pg_plan_query?
If query_text will be NULL, we need to add codes to avoid errors in
pgss_store like as current patch. If query_text will not be NULL, we should
add Assert in pg_plan_query so that other developers can notice that they
would not mistakenly set query_text as NULL even without using pgss_planning
counter.
