Removes a type from the system catalogs.
DROP TYPE typename [, ...]
typename
The name of a type you wish to remove. You may drop multiple types by specifying their names in a comma-delimited list.
Use the DROP TYPE
command to remove a type from the database system.
Only the owner of a type, or a superuser, is allowed to do this.
If you are logged in as a superuser, you will be able to drop system types. However, doing so can cause extreme instability. Be careful!
The DROP TYPE
command will not automatically remove any objects that
reference the data type, or types, that you are dropping. Once a data type is removed,
anything that uses it will most likely stop working. Be sure to remove objects that depend on
types that you drop, and be sure not to drop types used by objects you wish to keep.
