DROP TYPE
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 EXISTSDo not throw an error if the type does not exist. A notice is issued in this case.
nameThe name (optionally schema-qualified) of the data type to remove.
CASCADEAutomatically drop objects that depend on the type (such as table columns, functions, operators).
RESTRICTRefuse 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 Postgres Pro extension. But note that much of the CREATE TYPE command and the data type extension mechanisms in Postgres Pro differ from the SQL standard.
