DROP SEQUENCE

Name

DROP SEQUENCE -- remove a sequence

Synopsis

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

Description

DROP SEQUENCE removes sequence number generators. A sequence can only be dropped by its owner or a superuser.

Parameters

IF EXISTS: Do not throw an error if the sequence does not exist. A notice is issued in this case.
name: The name (optionally schema-qualified) of a sequence.
CASCADE: Automatically drop objects that depend on the sequence, and in turn all objects that depend on those objects (see Section 5.13).
RESTRICT: Refuse to drop the sequence if any objects depend on it. This is the default.

Examples

To remove the sequence serial:

DROP SEQUENCE serial;

Compatibility

DROP SEQUENCE conforms to the SQL standard, except that the standard only allows one sequence to be dropped per command, and apart from the IF EXISTS option, which is a PostgreSQL extension.
