Syntax:
UNINSTALL COMPONENT component_name [, component_name ] ...

This statement deactivates and uninstalls one or more server
components. A component provides services that are available to the
server and other components; see
https://dev.mysql.com/doc/refman/8.0/en/server-components.html.
UNINSTALL COMPONENT is the complement of INSTALL COMPONENT. It requires
the DELETE privilege for the mysql.component system table.

Example:

UNINSTALL COMPONENT 'file://component1', 'file://component2';

For information about component naming, see [HELP INSTALL COMPONENT].

If any error occurs, the statement fails and has no effect. For
example, this happens if a component name is erroneous, a named
component is not installed, or cannot be uninstalled because other
installed components depend on it.

A loader service handles component unloading, which includes removing
uninstalled components from the mysql.component system table that
serves as a registry. As a result, unloaded components are not loaded
during the startup sequence for subsequent server restarts.
