When using the PQlib system with Postgres 4.1, execution of the
PQendcopy() function causes the program executing PQendcopy()
to hang, rather than allowing us to perform a second operation.
Has anybody else came across this problem, or can provide a
solution.
Cheers
Dave Nelson

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.)
