Change Postgres Driver

[mauza]

Firstly thank you for your work, this is an awesome project. We use google cloud and would like to use a different driver for connecting. Specifically:
https://pkg.go.dev/github.com/GoogleCloudPlatform/cloudsql-proxy/proxy/dialers/postgres
Is it an easy change to make the driver configurable or are there problems with dependencies and/or connection strings that introduce more complexity?
