It would be helpful to see the assignment to "con" as well as any other
assignments related to this. If you are using the DBI package, then what I
am talking about would be something like:
drv<-dbDriver("PgSQL")
con<-dbConnect(drb,user=...,password=...,dbname="test');

Normally that user is only for administration purposes. It does not
normally contain user tables such as "test". I would think that what you
needed would be your PostgreSQL user id. Or the id of the owner of the
"test" table.
