Agreed showing just search path and implicit schemas is pretty dumb.  I
think the issue was that every backend with a temp table was showing up,
pretty much swamping the actual schemas he is using.  The original
approach was to supress all temp schemas _except_ the ones already
visible, but was a hack using backend id.  The patch could easily be
modified to use current_schemas to restrict temp table display if people
think it is a good idea.
