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.

       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.

SEE ALSO
