我在使用 RStudio 上的 R 和使用包 RPostgreSQL 连接到我的 Amazon RDS PostgreSQL 数据库时遇到问题。
我在跑步：
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，我收到错误：
postgresqlNewConnection(drv, ...) 中的错误：RS-DBI 驱动程序：（无法在 dbname "mydbname" 上连接 myuser@.........us-west-2.rds.amazonaws.com）
请注意，我有正确的 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
这是我的会话信息：
