As a cloud platform AWS gives you very minimal number of steps to setup a DB in RDS. Creating a PostgreSQL can be done in three ways. Using AWS management console, AWS CLI or AWS API. We will look at each of these approaches one by one.

Using AWS management Console

AWS management console is the most convenient way to get started with RDS. You login to the AWS console using your AWS account details, locate the RDS service and then follow the steps shown below to create a PostgreSQL instance.

Step-1

Select the PostgreSQL Engine form the console.

Step-3

In this step you decide on the db instance class, amount of storage allocated also set the master password along with few other details.

Stpe—4

This is the final step when you mention the vpc and security settings, encryption, backup options and log export etc. For brevity the screen shot has been shortened showing only the final options.

In the final step we choose the create Data base option.

Using CLI

To create a PostgreSQL DB instance by using the AWS CLI, call the create-db-instance command with the parameters below.

aws rds create-db-instance 
    --db-instance-identifier pgdbinstance \
    --allocated-storage 20 \ 
    --db-instance-class db.t2.small \
    --engine postgres \
    --master-username masterawsuser \
    --master-user-password masteruserpassword

Using API

To create a PostgreSQL instance by using the Amazon RDS API, we call the CreateDBInstance action with the parameters as shown below.

https://rds.amazonaws.com/
    ?Action=CreateDBInstance
    &AllocatedStorage=20
    &BackupRetentionPeriod=3
    &DBInstanceClass=db.t2.small
    &DBInstanceIdentifier=pgdbinstance
    &DBName=mydatabase
    &DBSecurityGroups.member.1=mysecuritygroup
    &DBSubnetGroup=mydbsubnetgroup
    &Engine=postgres
    &MasterUserPassword=
    &MasterUsername=
    &SignatureMethod=HmacSHA256
    &SignatureVersion=4
    &Version=2013-09-09
    &X-Amz-Algorithm=AWS4-HMAC-SHA256
    &X-Amz-Credential=AKIADQKE4SARGYLE/20140212/us-west-2/rds/aws4_request
    &X-Amz-Date=20140212T190137Z
    &X-Amz-SignedHeaders=content-type;host;user-agent;x-amz-content-sha256;x-amz-date
    &X-Amz-Signature=60d520ca0576c191b9eac8dbfe5617ebb6a6a9f3994d96437a102c0c2c80f88d
