  • SaasRock uses Supabase as its PostgreSQL database provider, but there are a few things to be aware of when hosting in a Serverless environment like Vercel.

    Development Connection String

    Seed your remote database or test locally using the following Connection String configuration:

    DATABASE_URL="postgresql://{USER}:{PASSWORD}@{HOST}:5432/postgres"

    Production Connection String

    If you deploy your app to a serverless environment, you need to use the Connection Pooling configuration:

    DATABASE_URL=postgres://{USER}:{PASSWORD}@{HOST}:6543/postgres?pgbouncer=true

    Otherwise, you could get the following error:

    Remaining connection slots are reserved for non-replication superuser connections
    Connection slots error

    Database and Hosting regions should be the same

    In my case, I'm using Fly.io as my hosting provider, in the "iad", which is us-east-1 (Virginia).

    So my database region should be somewhere close to Virginia. Both Supabase and Fly use AWS so it's the same region: us-east-1.
