Large Files support - Invalid value "interface org.postgresql.PGConnection" for parameter "iface"

[JethroMV]

Hi, I'm trying to use slick-pg to use the Large Object Postgresl functionality, but keep getting the following exception, which I do not understand.

The exception is thrown from the following action, taken from . the README here.

    val driver = new LargeObjectSupport with ExPostgresProfile {}
    driver.buildLargeObjectUploadAction(inputStream)

I have also tried using the MyPostgresProfile example profile from the main README, which gives the same exception.

Thanks for any assistance.

@JethroMV are you using H2 driver? But slick-pg used pgjdbc driver's interface (check here and here).
