DROP SCHEMA(7) PostgreSQL 9.2.7 Documentation DROP SCHEMA(7)NAME
DROP_SCHEMA - remove a schema
SYNOPSIS
DROP SCHEMA [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP SCHEMA removes schemas from the database.
A schema can only be dropped by its owner or a superuser. Note that the owner can drop the schema (and thereby all contained objects) even
if he does not own some of the objects within the schema.
PARAMETERS
IF EXISTS
Do not throw an error if the schema does not exist. A notice is issued in this case.
name
The name of a schema.
CASCADE
Automatically drop objects (tables, functions, etc.) that are contained in the schema.
RESTRICT
Refuse to drop the schema if it contains any objects. This is the default.
EXAMPLES
To remove schema mystuff from the database, along with everything it contains:
DROP SCHEMA mystuff CASCADE;
COMPATIBILITY
DROP SCHEMA is fully conforming with the SQL standard, except that the standard only allows one schema to be dropped per command, and apart
from the IF EXISTS option, which is a PostgreSQL extension.

DROP TABLE(7) PostgreSQL 9.2.7 Documentation DROP TABLE(7)NAME
DROP_TABLE - remove a table
SYNOPSIS
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TABLE removes tables from the database. Only the table owner, the schema owner, and superuser can drop a table. To empty a table of
rows without destroying the table, use DELETE(7) or TRUNCATE(7).
DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is
referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view
entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)
PARAMETERS
IF EXISTS
Do not throw an error if the table does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of the table to drop.
CASCADE
Automatically drop objects that depend on the table (such as views).
RESTRICT
Refuse to drop the table if any objects depend on it. This is the default.
EXAMPLES
To destroy two tables, films and distributors:
DROP TABLE films, distributors;
COMPATIBILITY
This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the IF
EXISTS option, which is a PostgreSQL extension.
