trusty (7) DROP_TYPE.7.gz

NAME

       DROP_TYPE - remove a data type

SYNOPSIS

       DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

           Note
           The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

       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, 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 Postgres-XC extension inherited from PostgreSQL. But note that much of the CREATE TYPE
       command and the data type extension mechanisms in Postgres-XC differ from the SQL standard.
