code example in README.md is not usable as-is

Specifically the MyPostgresProfile snippet - to get this to work I had to make two changes:

import slick.basic.Capability

and

  override protected def computeCapabilities: Set[Capability] =
    super.computeCapabilities + slick.jdbc.JdbcCapabilities.insertOrUpdate

Running Slick 3.3.1 with Scala 2.12.7, if that matters. I can submit a pull request with this change but it wasn't clear to me if the current computeCapabilities override would work with different versions - although I believe the import is required anyway.

@natechols well, why I don't think it's a matter?
