Which of the following can be used to create a database within PostgreSQL
The easiest way to create a DB instance is to use the AWS Management Console. After you have created the DB instance, you can use standard SQL client utilities to connect to the DB instance, such as the pgAdmin utility. In this example, you create a DB instance running the PostgreSQL database engine called Show
There's no charge for creating an AWS account. However, by completing this tutorial, you might incur costs for the AWS resources that you use. You can delete these resources after you complete the tutorial if they are no longer needed. Contents
Creating a PostgreSQL DB instanceThe basic building block of Amazon RDS is the DB instance. This environment is where you run your PostgreSQL databases. You can use Easy create to create a DB instance running PostgreSQL with the AWS Management Console. With Easy create, you specify only the DB engine type, DB instance size, and DB instance identifier. Easy create uses the default settings for the other configuration options. When you use Standard create instead of Easy create, you specify more configuration options when you create a database, including ones for availability, security, backups, and maintenance. In this example, you use Easy create to create a DB instance running the PostgreSQL database engine with a db.r6g.large DB instance class. To create a PostgreSQL DB instance with Easy create
Connecting to a PostgreSQL DB instanceAfter Amazon RDS provisions your DB instance, you can use any standard SQL client application to connect to the instance. Following, you can find two ways to connect to a PostgreSQL DB instance. The first example uses pgAdmin, a popular open-source administration and development tool for PostgreSQL. You can download and use pgAdmin without having a local instance of PostgreSQL on your client computer. The second example uses psql, a command line utility that is part of a PostgreSQL installation. To use psql, make sure that you have PostgreSQL or the psql client installed on your client computer. Before you try connecting to the DB instance, make sure that the DB instance is associated with a security group that provides access to it. For more information, see Provide access to your DB instance in your VPC by creating a security group. In some cases, you might have difficulty connecting to the DB instance. If so, the problem is most often with the access rules that you set up. These reside in the security group that you assigned to the DB instance. If you didn't specify the appropriate security group when you created the DB instance, you can modify the DB instance to change its security group. For more information, see Modifying an Amazon RDS DB instance. If your DB instance is publicly accessible, make sure its associated security group has inbound rules for the IP addresses that you want to access it. If your DB instance is private, make sure its associated security group has inbound rules for the security group of each resource to access it. An example is the security group for an Amazon EC2 instance. For more information about connecting to a PostgreSQL DB instance, see Connecting to a DB instance running the PostgreSQL database engine. If you can't connect to your DB instance, see Troubleshooting connections to your RDS for PostgreSQL instance. Topics
Using pgAdmin to connect to a PostgreSQL DB instanceTo connect to a PostgreSQL DB instance using pgAdmin
Using psql to connect to a PostgreSQL DB instanceIf your client computer has PostgreSQL installed, you can use a local instance of psql to connect to a PostgreSQL DB instance. To connect to your PostgreSQL DB instance using psql, you provide host information, port number, access credentials, and the database name. You can obtain these details by following the first step in the procedure for Using pgAdmin to connect to a PostgreSQL DB instance The following format is used to connect to a PostgreSQL DB instance on Amazon RDS.
For example, the following command connects to a database called
Deleting a DB instanceAfter you connect to the sample DB instance that you created, delete it so you're no longer charged for it. To delete a DB instance with no final DB snapshot
