Man page for dbConnect is missing a section, cross-links do not work correctly

What steps will reproduce the problem?
1. In R type ?PostgreSQL to look at the documentation on the PostgreSQL object, 
for example.
2. This page looks OK.  Now try the links at the bottom to look at the 
PostgreSQL versions of the DBI methods - for example, click on dbConnect
3. Note that you have linked to the dbConnect page describing the DBI base 
method, not the PostgreSQL version of this method.
4. If instead you click on the index link at the bottom of the PostgreSQL page, 
then you get to the correct table of documentation for RPostgreSQL.  For 
example, click on dbConnect-methods.  This brings you to the correct page 
describing dbConnect() for PostgreSQl.  However, if you click on the links on 
this page (e.g. click on dbCommit) you are back at the DBI base class version 
of dbCommit().

What is the expected output? What do you see instead?
I would have expected to see info on the RPostgreSQL versions of the DBI 
methods when I click on the links on the documentation pages for RPostgreSQL 
methods in the package.

What version of the product are you using? On what operating system?
Using Eclipse 4.2,1 on Windows 7 64-bit.  Using R 2.15.2.  RPostgreSQL 0.4 
compiled on R 2.15.3.
