   In theory it should work, in practice, I don't know.
   Since pg_class is really close to the heart of the system, it   is created a little different during bootstrap. This
causes,   that  setting  relacl  to  storage  'x' doesn't automatically   create  a  toast  relation  for  it  during
bootstrap.  And   therefore,  the  toaster  should  only try to compress, never   move out (to where?).
 
   Someone could later create such  a  toast  table  with  ALTER   TABLE  ...   if  he wants to give it a try. And we
couldwarn   him not to do so before we really stress tested it.
 
   Is that a compromise?
