Genie web framework. How to establish a connection pool to postgres?

I started playing with Genie this morning. It looks great. I was wondering if someone knows how to establish a connection pool to Postgres. Do I use LibPQ.jl directly, if I don’t need an ORM, such as the SearchLight ORM? And, if so, how do I create a connection pool? If I use SearchLight, does it create a connection pool automatically? If I understand correctly, connecting on every request is not a very efficient way to do for a web app.

Thank you very much.
