What value does it provide to have it shown in a \dn listing? Temp
tables are globally visible across schemas and there's no point to
looking inside of a temp schema that isn't a proc's temp schema.

There is only one pg_catalog, pg_toast, and information_schema schema.
Those schemas yield useful information that can only be fetched via
their respective schemas. pg_temp_* doesn't meet this criteria since
pg_temp_*'s tables are visible outside of their schema. Why wouldn't
you want to hide pg_temp_*?
