NAME
DROP TYPE - remove a data typeSYNOPSIS
DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TYPE will remove a user-defined data type. Only the owner of a type can remove it.
PARAMETERS
- IF EXISTS
- Do not throw an error if the type does not exist. A notice is issued in this case.
- name
- The name (optionally schema-qualified) of the data type to remove.
- CASCADE
- Automatically drop objects that depend on the type (such as table columns, functions, operators).
- RESTRICT
- Refuse to drop the type if any objects depend on it. This is the default.
EXAMPLES
To remove the data type box:
DROP TYPE box;
COMPATIBILITY
This command is similar to the corresponding command in the SQL standard, apart from the IF EXISTS option, which is a PostgreSQL extension. But note that the CREATE TYPE command and the data type extension mechanisms in PostgreSQL differ from the SQL standard.
