Log Message:
-----------
Fix an oversight in the original implementation of performMultipleDeletions():
the alreadyDeleted list has to be passed down through
deleteDependentObjects(), else objects that are deleted via auto/internal
dependencies don't get reported back up to performMultipleDeletions().
Depending on the visitation order, this could cause the code to try to delete
an already-deleted object, leading to strange errors in DROP OWNED (typically
"cache lookup failed for relation NNNNN" or similar). Per bug #4289.
Patch for back branches only. This code has recently been rewritten in HEAD,
and doesn't have this particular bug anymore.
