What actual issue could occur if free_parsestate() is not called there?

Since pstate->p_target_relation does not seem to be used afterward,
omitting free_parsestate() appears mostly harmless to me. Bascailly
calling free_parsestate() after make_parsestate() seems intuitive,
but from a quick grep I found several places that call make_parsestate()
without a corresponding free_parsestate().
