Aha! Okay, glad I don't need to track that down.

Which references? libpq-oauth should be the only thing using Curl symbols:

    $ nm src/interfaces/libpq/libpq.a | grep --count curl
    0
    $ nm src/interfaces/libpq-oauth/libpq-oauth-18.a | grep --count curl
    116

That implements the flow. You'll need to link that into your
application or it will complain about missing flow symbols. (I don't
think there's an easy way to combine the two libraries in our Autoconf
setup; the only ways I can think of right now would introduce a
circular dependency between libpq and libpq-oauth...)

Thanks!
