If you're on 8.2.not-the-latest or 8.3.not-the-latest, this is probably
a known bug. Update.

* src/backend/catalog/: dependency.c (REL8_3_STABLE), dependency.c
(REL8_2_STABLE): 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.
