DROP SEQUENCE
DROP SEQUENCE — remove a sequence.
Supported syntax
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.
RESTRICT-
Refuse to drop the sequence if any objects depend on it. This is the default.
Examples
To remove the sequence seq:
DROP SEQUENCE seq;
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.
