我已经将文件配置为使用mysql作为postgressql的默认数据库，并且在创建数据库时显示以下错误

C:\Users\kusuma\.mix\hello_phoenix>mix ecto.create
warning: found quoted keyword "test" but the quotes are not required. Note that keywords are always atoms, eve
n when quoted, and quotes should only be used to introduce keywords with foreign characters in them
