Sorry for the late asnwer.

If I remember correctly the libpq docs don't say if it is possible to
retrieve the number of inserted columns and we're not sending data
line-by-line but as chunks so counting the lines isn't possible. Maybe
(a big maybe) the final PGresult contains that but I can't find this
documented anywhere. We'll need to instrument psycopg to print PGresult
fields and do a bit of guesswork.

  Those who do not study Lisp are doomed to reimplement it. Poorly.
