Just looking a bit, it seems that Rdbi has this statement in 'zzz.R':
.onLoad <- function(lib, pkg) {
  # Changed by JZ from Rdbi.PgSQL to RdbiPgSQL
  autoload("PgSQL", "RdbiPgSQL")
# autoload("MySQL", "Rdbi.MySQL")
.....

And in RdbiPgSQL NAMESPACE:
import(Rdbi)

Is this causing the circular dependency?
