That does seem like a lot --- what sort of types are they?  Scalar,
composite, what?  It's fairly likely that no one has tried to optimize
pg_dump for such a case.

It'd be helpful if you could recompile pg_dump with profiling enabled
(-pg compiler switch) and get a gprof profile to show where the time
is going.
