java - 如何在 doobie 数据库 url 中设置端口号？

Question

我的 Postgresql 服务器在端口 6000（不是默认端口 5432）上运行。如何设置将此端口号放入 doobie jdbc url？

val xa = Transactor.fromDriverManager[IO](
  "org.postgresql.Driver",     // driver classname
  "jdbc:postgresql:databasename",     // connect URL (driver-specific)
  "user",                  // user
  "password"                           // password

这是错误消息：

[info] - should success *** FAILED ***
[info]   org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

端口是连接 url 的一部分：

val xa = Transactor.fromDriverManager[IO](
  "org.postgresql.Driver",     // driver classname
  "jdbc:postgresql://localhost:5432/world",     // connect URL (driver-specific)
  "user",                  // user
  "password"                           // password
