DROP_SEQUENCE: remove a sequence

Command to display DROP_SEQUENCE manual in Linux: $ man 7 DROP_SEQUENCE

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.
