go - Sharing a globally defined db conn with multiple packages

Question

I've read a few StackOverflow answers on how we handling the db connection. Since it's a pool, we can define it globally and use it in multiple goroutines and it's safe.

The issue I'm having is that I have split my REST API into multiple packages. Each of these packages require a db connection, so I open a database connection in the startup. But even if I define the connection globally, it's only at the package level. What can I do to potentially share it among multiple packages?

For some context I'm using the PostgreSQL driver and gin-gonic in my application.
