How cash strapped? Personally, I would just use something managed like AWS's RDS for PostgreSQL https://aws.amazon.com/rds/postgresql/ https://aws.amazon.com/rds/postgresql/ Then you don't need to worry too much about administrative tasks. As a bonus, you can start out small and easily scale as you grow, versus self-managed. It doesn't have to be AWS. You can find similar offerings from pretty much any cloud provider.
