Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL, and SQL Server. It automates time-consuming tasks like patches, updates, backups, and replicas, while providing high performance and availability for your applications.
Ensure you have the necessary IAM permissions to create and manage Cloud SQL instances. The Cloud SQL Admin (roles/cloudsql.admin) role provides full access to Cloud SQL resources.
bash gcloud services enable sqladmin.googleapis.com --quiet
bash gcloud sql instances create INSTANCE_NAME \ --database-version=POSTGRES_18 \ --cpu=2 \ --memory=7680MiB \ --region=REGION \ --quiet
Because this is a Cloud SQL for PostgreSQL instance, the default admin user is postgres: bash gcloud sql users set-password postgres \ --instance=INSTANCE_NAME --password=PASSWORD \ --quiet
bash gcloud sql databases create DATABASE_NAME \ --instance=INSTANCE_NAME \ --quiet
You need the instance connection name (which is formatted as PROJECT_ID:REGION:INSTANCE_NAME) to connect using the Cloud SQL Auth Proxy. Retrieve it with the following command: bash gcloud sql instances describe INSTANCE_NAME \ --format="value(connectionName)" \ --quiet
The Cloud SQL Auth Proxy must be running to be able to connect to the instance. In a separate terminal, start the proxy using the connection name: bash ./cloud-sql-proxy INSTANCE_CONNECTION_NAME
With the proxy running, connect using psql in another terminal: bash psql "host=127.0.0.1 port=5432 user=postgres dbname=DATABASE_NAME password=PASSWORD sslmode=disable"

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +50 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
