pgsql: Save a few cycles in EXPLAIN and related commands by not

-----------
Save a few cycles in EXPLAIN and related commands by not bothering to form
a physical tuple in do_tup_output().  A virtual tuple is easier to set up
and also easier for most tuple receivers to process.  Per my comment on
Robert Haas' recent patch in this code.
