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

-
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 5.14).
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;

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.
