[EOS/Discontinuation] Some ApsaraDB RDS for PostgreSQL instance types are no longer available for purchase from April 29, 2022

When you purchase an ApsaraDB RDS for PostgreSQL instance, you can no longer select an end-of-sale instance type.

You can continue to use existing RDS instances that use end-of-sale instance types. However, you cannot select an end-of-sale instance type in specific scenarios. For example, you cannot select an end-of-sale instance type when you restore the data of an RDS instance, upgrade the major engine version of an RDS instance, or create a read-only RDS instance. For more information, see Restore data of an ApsaraDB RDS for PostgreSQL instance,Upgrade the major engine version, and Create a read-only ApsaraDB RDS for PostgreSQL instance.

The instance types that provides 1 core and 2 GB of memory can no longer meet the requirements for performance and stability. Therefore, the following ApsaraDB RDS for PostgreSQL instance types that provide 1 core and 2 GB of memory will be discontinued: pg.n2.small.2c and rds.pg.s1.small. You can purchase RDS instances with higher specifications.

After the pg.n2.medium.2c instance type is discontinued, we recommend that you purchase RDS instances that use the pg.x2.medium.2c or pg.n2.2c.2m instance type.
