handling RS-DBI errors

Sorry for not being more specific in my first email. I'm using RPostgreSQL
and Ubuntu 10.04.
The problem is not just the error message prints, but also that R seems to
have no idea that an error occurred at all. An error message prints in spite
of the silent=T option, and what's much worse, the class of ?`out' is NULL.

library(RpgSQL)
con <- dbConnect(pgSQL())
out <- try(dbGetQuery(con, "select * from doesnotexist"), silent = TRUE)
class(out)

R.version.string

win.version()
