SEQUENCE(7)					  PostgreSQL 9.2.7 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.

       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.

NAME

       DROP_EXTENSION - remove an extension

SYNOPSIS

       DROP EXTENSION [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP EXTENSION removes extensions from the database. Dropping an extension causes its component objects to be dropped as well.

       You must own the extension to use DROP EXTENSION.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the extension does not exist. A notice is issued in this case.

       name
	   The name of an installed extension.

       CASCADE
	   Automatically drop objects that depend on the extension.

       RESTRICT
	   Refuse to drop the extension if any objects depend on it (other than its own member objects and other extensions listed in the same
	   DROP command). This is the default.

EXAMPLES

       To remove the extension hstore from the current database:

	   DROP EXTENSION hstore;

       This command will fail if any of hstore's objects are in use in the database, for example if any tables have columns of the hstore type.
       Add the CASCADE option to forcibly remove those dependent objects as well.

COMPATIBILITY

       DROP EXTENSION is a PostgreSQL extension.
