Yeah, pgsql just doesn't have that level of isolation built into, and
probably won't for some time, as most users don't need it. There are
a few options.

1: Set up a replicant with slony of just the tables you want them to
see. If you only want the view, you could use a materialized view on
the source and replicate that.
2: Use a web service to expose the data set without exposing the
database directly.

No matter how much security my db had I don't think I'd ever let a
remote customer access it directly (the main db that is, a clone with
just the right data is a different story.)
