If we did it like that, tab completion would fail to see the session's
temp tables, or objects created in the current open transaction.
People might bitch about using twice as many connections, too, although
likely you could finesse that by only opening the second connection if
tab completion actually happens (so that only interactive sessions have
one). Still, the local-objects problem seems like a fatal objection.
