Another odd datapoint on this server. Things were running pretty good
but an application crashed on a missing view.  Trying to recreate the
view, I got:

CREATE OR REPLACE VIEW vw_ApartmentQueueLastGood AS
  SELECT ...

ERROR:  type "vw_apartmentqueuelastgood" already exists
HINT:  A relation has an associated type of the same name, so you must
use a name that doesn't conflict with any existing type.

...which was pretty strange.  I had to manually delete the pg_type
record in order to create the view.   I'm getting more reports of
'could not open relation with oid=X' errors so I could be facing data
corruption :(.
