(MatchError) no match of right hand side value: {:error, {:postgrex, {'no such file or directory', 'postgrex.app'}}} , when running 'mix ecto.migrate'

I am new to the Elixir, here's what my config file, and Repo. and a migration looks like

use Mix.Config

config :zeri, ecto_repos: [Zeri.Repo]

database_url = "postgresql://postgres:9835674725@localhost:5432/kaisa_db"
config :zeri, Zeri.Repo, url: database_url

defmodule Zeri.Repo do
  use Ecto.Repo,
    otp_app: :zeri,
    adapter: Ecto.Adapters.Postgres
end

defmodule Zeri.Repo.Migrations.First do
  use Ecto.Migration

  def change do
    execute("CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\";", "")

    create(table(:users, primary_key: false))
      add :id, :uuid, primary_key: true, default: fragment("uuid_generate_v4()")
      add :username, :text, null: true

    end
  end
end

when running 'mix ecto.migrate' i'm getting the following error
