[R] Rdbi/RdbiPgSQL updates

[Markus Neteler]

To get the Rdbi/RdbiPgSQL 1.0.1 interface from BioConductor
functional, I would like to suggest some fixes.
Find patches and the updated packages here:

 http://mpa.itc.it/markus/tmp/rdbi/

Changes

 Rdbi:
  - fixed load of RdbiPgSQL   (wrong name)
  - fixed dbConnectionInfo()  (typo)

 RdbiPgSQL:
  - fixed table export to PostgreSQL
  - added make.names() to polish column names for R usage

(maybe some of these patches are already in the 
 BioConductor-CVS)

Now the interface seems to work smoothly.

Thanks to Steno Fontanari and Dirk Eddelbuettel for their assistance.

Kind regards

 Markus Neteler
