Thank you for pointing to this file.

This is correct.

My feeling is that installing rgdal from source on Windows is going to 
take (much) more time learning about compilers and their peculiarities 
than using command line utilities distributed in the PostGIS bundle for 
Windows:

http://postgis.net/windows_downloads

There shp2pgsql and pgsql2shp are mentioned, but as GDAL is also 
installed, ogr2ogr would let you use other intermediate file formats than 
ESRI Shapefiles, provided that the drivers are in the rgdal Windows binary 
package. Writing a small R function to run and check system() or system2() 
to run the command line utilities from inside R will be much easier than 
installing rgdal from source unless you know a lot about the compliers 
used with PostGIS and R. It also removes concerns that some components may 
be 32-bit or 64-bit.

Hope this helps,

Roger
