You could do this completely within R by installing both rgdal and
rpostresql (http://code.google.com/p/rpostgresql/). You'll have to split
your queries in an attribute part (rpostgresql) and a geometry part
(rgdal, returning sp items) and combining them afterwards. I have never
done this but it should work. Moreover, one of the developers of
rpostgesql is Joe Conway, the maker of PL/R. He'll certainly anser
questions on the PL/R mailing list.
