Syntax
------ 
UNINSTALL PLUGIN [IF EXISTS] plugin_name
 
Description
----------- 
This statement removes a single installed plugin. To
uninstall the whole library which contains the plugin, use
UNINSTALL SONAME. You cannot uninstall a plugin if any table
that uses it is open.
 
plugin_name must be the name of some plugin that is listed
in the mysql.plugin table. The server executes the plugin's
deinitialization
function and removes the row for the plugin from the
mysql.plugin
table, so that subsequent server restarts will not load and
initialize
the plugin. UNINSTALL PLUGIN does not remove the plugin's
shared library file.
 
To use UNINSTALL PLUGIN, you must have the
DELETE privilege for the mysql.plugin table.
 
IF EXISTS
 
If the IF EXISTS clause is used, MariaDB will return a note
instead of an error if the plugin does not exist. See SHOW
WARNINGS.
