Uninstalling Trusted Language Extensions for PostgreSQL

If you no longer want to create your own TLE extensions using TLE, you can drop the pg_tle extension and remove all artifacts. This action includes dropping any TLE extensions in the database and dropping the pgtle schema.

To drop the pg_tle extension and its schema from a database

  1. Use psql or another client tool to connect to the RDS for PostgreSQL DB instance. 

    psql --host=.111122223333.aws-region.rds.amazonaws.com --port=5432 --username=postgres --password --dbname=dbname

  2. Drop the pg_tle extension from the database. If the database has your own TLE extensions still running in the database, you need to also drop those extensions. To do so, you can use the CASCADE keyword, as shown in the following.

    DROP EXTENSION pg_tle CASCADE;

    If the pg_tle extension isn't still active in the database, you don't need to use the CASCADE keyword.

  3. Drop the pgtle schema. This action removes all the management functions from the database.

    DROP SCHEMA pgtle CASCADE;

    The command returns the following when the process completes.

    DROP SCHEMA

    The pg_tle extension, its schema and functions, and all artifacts are removed. To create new extensions using TLE, go through the setup process again. For more information, see Setting up Trusted Language Extensions in your RDS for PostgreSQL DB instance.
