问题描述
我在RStudio上使用R并使用软件包RPostgreSQL连接到我的Amazon RDS PostgreSQL数据库时遇到问题。
I am having trouble connecting to my Amazon RDS PostgreSQL database using R on RStudio and using the package RPostgreSQL.
我正在运行：
library("RPostgreSQL")
drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv, dbname="mydbname",
host="........us-west-2.rds.amazonaws.com", port=5432,
user="myuser", password="mypassword")
运行此行后，出现错误：
After running this line, I get the error:
请注意，我具有正确的dbname，主机，端口，用户和密码，因为我能够使用pgAdmin3连接到Amazon数据库
Note that I have the correct dbname, host, port, user and password because I am able to connect to the Amazon database using pgAdmin3
