Privileged accounts are granted the permissions to call the pg_ls_waldir() function. The scanning method that is used by the monitoring and alerting feature is optimized to improve CPU performance. The major version upgrade feature is optimized. For more information, see Upgrade the major engine version of an ApsaraDB RDS for PostgreSQL instance. This feature can be used to update extensions such as postgis and pgRouting with no downtime. This feature can also be used to update account permissions from PostgreSQL 9.4 to a later version with no downtime. The maximum length per log record is increased from 1,024 bytes to 4,096 bytes when SQL statements cause insufficient memory or unexpected exits.

This extension is used to clear tablespaces and mitigate table bloats. PostgreSQL 10 is supported by the mysql_fdw extension. The mysql_fdw extension is updated to version 1.1. The major version upgrade feature is provided to migrate the user permissions, the mysql_fdw and oss_fdw extensions, and the permissions on these extensions with no downtime. For more information, see Upgrade the major engine version. Bug fixes: The bug due to which the oss_fdw extension cannot be used after a minor engine version update or a major engine version upgrade is fixed.
20210228	PostgreSQL 10.14 is supported. New features: The extensions of GanosBase are updated to version 3.6. Bug fixes: The bug that triggers log-related online alerts if the archive_mode parameter is set to on is fixed.

20201130	PostgreSQL 10.14 is supported. New features: Privileged accounts are granted the permissions to create accounts that have the REPLICATION permission on data streams. Privileged accounts are granted the permissions to create event triggers. The rds_auditlog_max_query_length parameter is added. This parameter specifies the maximum length per audit log record. An updated pg_cron extension is provided. After the update, this extension can be used to create and run cross-instance tasks. In addition, this extension provides a table named cron.job_log from which users can view task records. The pg_freespacemap extension is supported. Spatio-temporal memory topology indexes are supported by the extensions of GanosBase. The extensions of GanosBase are updated to version 3.2. Bug fixes: The bug due to which DTS reports check errors when more than one child transaction is started or committed during data migration is fixed. The CVE-2020-14349 vulnerability is fixed. This vulnerability prevents ApsaraDB RDS from cleaning search paths in an expected manner during logical replications. The CVE-2020-14350 vulnerability is fixed. This vulnerability allows the `CREATE EXTENSION` statement to contain uncontrolled search path elements. The CVE-2020-25695 vulnerability is fixed. Attackers can exploit this vulnerability to create permanent objects and call all SQL functions by using the credentials of a superuser account.

20200212	PostgreSQL 10.9 is supported. New features: A specified number of connections can be reserved for the rds_superuser role. If users assume this role, they can log on to an RDS instance to troubleshoot issues even if the number of established connections to the RDS instance reaches the upper limit.

Bug fixes: The bug due to which the pg_hint_plan extension cannot be installed is fixed.

PostgreSQL 9.4

AliPG version	Configuration
20210531	Performance improvements: The major engine version upgrade feature is optimized. For more information, see Upgrade the major engine version.
