Does there exist an oracle $A$ such that $(P^{\#P})^{A} \neq PSPACE^{A}$? Background


  We know that $P^{\#P} \subseteq PSPACE$.
  
  In addition, we known from
  Toda's theorem that $PH \subseteq P^{\#P}$.
  
  For more background on $\#P$, see here:

Question


  Does there exist an oracle $A$ such that $(P^{\#P})^{A} \neq PSPACE^{A}$?
On popular request, here is my comment as an answer:

There is an oracle separating $\mathrm{PP}$ from $\mathrm{PSPACE}$: Jacobo Toran, A combinatorial technique for separating counting complexity classes, ICALP 1989. The best result for $\mathrm{P}^\mathrm{PP}$ that I know is a conditional result by Heribert Vollmer: Relating polynomial time to constant depth. TCS, 207: 159-170, 1998.
