6 DROP_SEQUENCE - remove a sequence
7
9 DROP SEQUENCE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
10
12 DROP SEQUENCE removes sequence number generators. A sequence can only
13 be dropped by its owner or a superuser.
14
16 IF EXISTS
17 Do not throw an error if the sequence does not exist. A notice is
18 issued in this case.
19
20 name
21 The name (optionally schema-qualified) of a sequence.
22
23 CASCADE
24 Automatically drop objects that depend on the sequence, and in turn
25 all objects that depend on those objects (see Section 5.14).
26
27 RESTRICT
28 Refuse to drop the sequence if any objects depend on it. This is
29 the default.
30
32 To remove the sequence serial:
33
34 DROP SEQUENCE serial;
35
37 DROP SEQUENCE conforms to the SQL standard, except that the standard
38 only allows one sequence to be dropped per command, and apart from the
39 IF EXISTS option, which is a PostgreSQL extension.
