[R] R and PostGresQL

[Sean Davis]

Sorry for the simple question:

What is the "standard" package for interfacing with PostGreSQL (most
up-to-date)?  There appear to be at least three with different names:

Rdbi.PgSQL
RdbiPgSQL (available as part of BioConductor)
RPgSQL (On the home page, no longer maintained in favor or Rdbi)

The R and database developer page (http://developer.r-project.org/db/) was
last updated in 2001, it appears.  The R Import-export manual addresses
RPgSQL, but not the other flavors mentioned above.

I am sure I have missed some key page stating the obvious.... Thanks in
advance for clarification.
