    Remove dead code for temporary relations in partition planning · fc057b2b
    Michael Paquier authored
    Since recent commit 1c7c317c, temporary relations cannot be mixed with
    permanent relations within the same partition tree, and the same counts
    for temporary relations created by other sessions, which the planner
    simply discarded.  Instead be paranoid and issue an error, as those
    should be blocked at definition time, at least for now.
    
    At the same time, a test case is added to stress what has been moved
    when expand_partitioned_rtentry gets called recursively but bumps on a
    partitioned relation with no partitions which should be handled the same
    way as the non-inheritance case.  This code may be reworked in a close
    future, and covering this code path will limit surprises.
