**Example 1: To create an Aurora PostgreSQL primary DB cluster**
The following ``create-db-cluster`` example creates an Aurora PostgreSQL SQL primary DB cluster that's compatible with Aurora Serverless v2 and Aurora Limitless Database. ::
aws rds create-db-cluster \
--db-cluster-identifier my-sv2-cluster \
--engine aurora-postgresql \
--engine-version 15.2-limitless \
--storage-type aurora-iopt1 \
--serverless-v2-scaling-configuration MinCapacity=2,MaxCapacity=16 \
--enable-limitless-database \
--master-username myuser \
--master-user-password mypassword \
--enable-cloudwatch-logs-exports postgresql

**Example 2: To create the primary (writer) DB instance**
The following ``create-db-instance`` example creates an Aurora Serverless v2 primary (writer) DB instance. When you use the console to create a DB cluster, Amazon RDS automatically creates the writer DB instance for your DB cluster. However, when you use the AWS CLI to create a DB cluster, you must explicitly create the writer DB instance for your DB cluster using the ``create-db-instance`` AWS CLI command. ::
aws rds create-db-instance \
--db-instance-identifier my-sv2-instance \
--db-cluster-identifier my-sv2-cluster \
--engine aurora-postgresql \
--db-instance-class db.serverless

**Example 3: To create the DB shard group**
The following ``create-db-shard-group`` example creates a DB shard group in your Aurora PostgreSQL primary DB cluster. ::
aws rds create-db-shard-group \
--db-shard-group-identifier my-db-shard-group \
--db-cluster-identifier my-sv2-cluster \
--max-acu 768
Output::
{
