Issue using EctoInterval: (Mix) Hex dependency resolution failed

I’m trying to use the EctoInterval package but I get the following error when attempting to compile the dependency:

Because "the lock" specifies **postgrex 0.17.5** and **ecto_interval >= 0.2.5** depends on **postgrex ~> 0.14.0 or ~> 0.15.0 or ~> 0.16.0**, **the lock** is incompatible with **ecto_interval >= 0.2.5**.
And because **your app** depends on **the lock**, **ecto_interval >= 0.2.5** is forbidden.
So, because **your app** depends on **ecto_interval ~> 0.2.5**, version solving failed.
** **(Mix) Hex dependency resolution failed**

How would I use Postgres interval types without this library?

According to this PR, it doesn’t require any changes other than bumping the version the package’s mix.exs:

Alternatively, the necessary part of the library is one .ex file (two if you count the corresponding tests). You could copy them directly into your project

Copy and pasting into my project is what I decided to do
