one thing that isn't terribly clear (ha, understatement) in the 
documentation is the fact that PQendcopy should only be used if 
you are doing copy with the stdin/stdout keywords.  copy to/from 
a file works just like any other query; if you call PQendcopy in
that case, the first thing libpq does is read from the connection,
and i would expect that that would hang.  (if that's not the
problem, then i have no idea.  both kinds of copy are exercised 
in the regression tests.)
