Well, that is not surprising in itself -- InitTempTableNamespace calls
RemoveTempRelations to cleanup from a possibly crashed previous backend
with the same ID. So that part of the backtrace looks normal to me
(unless there is something weird going on, which might very well be the
case).
It looks to me like you might have leftover pg_depend entries without
the corresponding entries in other catalogs (pg_class, etc). No idea
how that might happen, but maybe it's a starting point to investigate.
