RPostgres中是否有一个函数可以为Postgres中的表创建/标识主键？

# 安装和加载RPostgres包
install.packages("RPostgres")
library(RPostgres)

# 连接到Postgres数据库
con <- dbConnect(RPostgres::Postgres(), dbname = "your_database", host = "your_host", port = your_port, user = "your_username", password = "your_password")

# 创建表并指定主键
dbCreateTable(con, "your_table", 
              name = c("id", "name", "age"), 
              type = c("integer", "character", "integer"), 
              primaryKey = "id")

# 关闭数据库连接
dbDisconnect(con)
