DROP SEQUENCE(7)         PostgreSQL 16.2 Documentation        DROP SEQUENCE(7)

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 5.14).

       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;

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.
