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.
