The backend does keep a temp table name mapping, but it's hidden in an
internal data structure that there's no way to read out.
Rather than invent some way to make that mapping visible, I have been
thinking that it might be possible to dispense with the special mapping
altogether once we have schemas (which hopefully will happen for 7.2).
I am imagining that temp tables might become ordinary tables that live
in a per-backend schema. I haven't tried to work out the details yet,
though.
