There is just one PostgreSQL wire protocol. Different libraries such
as ODBC, libpq etc just give you a different API for using it. There
shouldn't be too much difference in bandwidth usage between the APIs
in the general case.
So your app should work fine, but pay very careful attention to
security anytime you expose the database directly to the 'net at
large. Use the 'md5' password scheme, and, if you can, restrict the
allowed IPs in pg_hba.conf to valid client addresses.
