:How to use OSS to expand the tablespace of a PostgreSQL instance

Last Updated:May 18, 2022

Overview

This topic describes how to use Alibaba Cloud Object Storage Service (OSS) to expand the tablespace of a PostgreSQL instance.

Details

Take note of the following items:

  • Before you perform high-risk operations such as modifying the specifications or data of an Alibaba Cloud instance, we recommend that you check the disaster recovery and fault tolerance capabilities of the instance to ensure data security.
  • Before you modify the specifications or data of an Alibaba Cloud instance, such as an Elastic Compute Service (ECS) instance or an ApsaraDB RDS instance, we recommend that you create snapshots or enable backups for the instance. For example, you can enable log backups for an ApsaraDB RDS instance.
  • If you have granted specific users the permissions on sensitive information, such as usernames and passwords, or submitted sensitive information in the Alibaba Cloud Management Console, we recommend that you modify the sensitive information at the earliest opportunity.

You can use OSS to expand the tablespace of a PostgreSQL instance, breaking the 2TB space limit. For more information, see the following topics:
