DROP EXTENSION
Removes an extension from a database.
Synopsis
DROP EXTENSION [IF EXISTS] <name> [, ...] [CASCADE | RESTRICT]Description
DROP EXTENSION removes extensions from the database.
Dropping an extension causes its component objects to be dropped as well.
The required supporting extension files that were installed to create the extension are not deleted. The files must be manually removed from cluster hosts.
You must own the extension to use DROP EXTENSION.
This command fails if any of the extension objects are in use in the database.
For example, if a table is defined with columns of the extension type.
Add the CASCADE option to forcibly remove those dependent objects.
Before issuing a DROP EXTENSION with the CASCADE keyword, you should be aware of all objects that depend on the extension to avoid unintended consequences.
