Add a new column to pg_class just for orphan tables? Sure sounds
overkill.
Maybe a bit in the pgstats entry for the table ...? It still seems like
useless bloat to me.
I wonder if we can find out whether a temp table is orphaned by some
other means (a query against catalogs + list of active backends? It
still needs to know whether the table was created by this backend or a
previous one.)
