Supported Plugins

The following table lists the plugins supported by the latest minor versions of RDS for PostgreSQL. You can use SELECT name FROM pg_available_extensions; to view the plugins supported by your DB instance.

Before using the mysql_fdw, oracle_fdw, pgsql-ogr-fdw, postgres_fdw, and tds_fdw plugins, ensure that the server IP addresses of the two PostgreSQL DB instances are in the same VPC and subnet.

Plugin Description

postgis
- When postgis is created, the following plugins are created at the same time:
  postgis
  
  postgis_topology
  
  fuzzystrmatch
  
  postgis_tiger_geocoder
  
  address_standardizer
  
  address_standardizer_data_us
- After the postgis plugin is created on the primary DB instance, you need to disconnect the connection from the standby DB instance first and re-establish a connection to update the search_path setting.
- For PostgreSQL Enhanced Edition DB instances, you need to set empty_is_null to OFF on the console before creating the postgis plugin.
earthdistance
To install the earthdistance plugin, you must install the cube plugin first.
cube
If the earthdistance plugin has been installed, deleting the cube plugin will cause the earthdistance plugin to be unavailable.
timescaledb
The timescaledb plugin does not support the TSL protocol. For more information, see APIs Not Supported by the timescaledb Plugin.
wal2json
This plugin is a logical replication plugin. You can directly use it without installing it through control_extension.
