DROP TYPE(7) PostgreSQL 15.7 Documentation DROP TYPE(7)
NAME
DROP_TYPE - remove a data type
SYNOPSIS
DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TYPE removes 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, and operators), and in turn all objects that
depend on those objects (see Section 5.14).
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 much of the CREATE TYPE command and the data
type extension mechanisms in PostgreSQL differ from the SQL standard.
