We’re migrated our elixir app to latest version along with dependencies. While upgrading postgrex from 0.13 to 0.16 we’re facing issue to setup pool. Previously we have db_connection 1.3 which supports DBConnection.Poolboy as a way of pool connection manager.
Upgrad:

  db_connection 1.1.3  => 2.4.2 (major)
  postgrex 0.13.5 => 0.16.3 (minor)

What is the most simple and actual way to setup connection pool? Thanks

You should be able to use Postgrex.start_link and it will start a pool using this module: DBConnection.ConnectionPool — db_connection v2.4.2. You can configure the pool size with the :pool_size option.
