Yeah, that's just the CREATE TEMP TABLE doing what it's supposed to do.
The problem is presumably that a prior DROP operation failed to remove
the pg_type row associated with a previous temp table of the same name
... but why that would happen is still really unclear.
Does your application drop these temp tables explicitly, or leave them
to be dropped automatically during commit? It might be interesting to
see whether changing that makes any difference. I'm also curious
whether the transaction that makes the temp table is ever rolled back
instead of committed.
