Heroku 포스트 그레스 관계 "information_schema.session_state"가 존재하지 않습니다.

Question

Ktor 백엔드를 Heroku postgres db로 이동하려고합니다. 여기에 전체 응용 프로그램 코드 :

https://github.com/MarcinMoskala/KotlinAcademyApp/tree/master/backend

는 Heroku가 포스트 그레스로 이동하려면, 나는이 예제 프로젝트를 기반으로 :

https://github.com/orangy/ktor-heroku-start

나는 다음에 내 데이터베이스 구성을 변경 :

private val config = application.environment.config.config("database") 

private val poolSize = config.property("poolSize").getString().toInt() 

private val hikariConfig = HikariConfig().apply { 
    val url = System.getenv("JDBC_DATABASE_URL") ?: config.property("connection").getString() 
    application.log.info("DB url is $url") 
    jdbcUrl = url 
    maximumPoolSize = poolSize 
    validate() 
} 

private val dataSource = HikariDataSource(hikariConfig) 

private val connection: DatabaseConnection = H2Connection { dataSource.connection } 

private val dispatcher = newFixedThreadPoolContext(poolSize, "database-pool") 

init { 
    connection.transaction { 
     databaseSchema().create(listOf(NewsTable, FeedbackTable, TokensTable)) 
    } 
} 

그리고 postgressql 종속성을 추가했습니다 :

compile "org.postgresql:postgresql:9.4-1201-jdbc4" 

(10)는 로컬 아직도 내가 Heroku가 그것을 누르면 그때 결과 다음과 같은 한 SQLite는 데이터베이스를 생성되지만 : 당신은 위해 Postgress에 H2Connection을 사용할 수 없습니다
