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.
