And I'd prefer keep the name of the namespace in the error message, because the information is helpful. >>> I thought that auto_vacuum wlll drop all >>> the temp table schema but it is not drooping. >> >> Generally speaking, once a particular pg_temp_N schema exists it's >> never dropped, just recycled for use by subsequent sessions. > > Okay. Understood. Thanks for clarification. Please see RemoveTempRelations() for the details, which uses PERFORM_DELETION_SKIP_ORIGINAL to avoid a drop of the temp schema, and just work on all the objects the schema includes. And committed down to 9.4. We use much more "temporary schema" in error messages actually, so I have switched to that. -- Michael
