NAME
DROP TABLE - remove a table
SYNOPSIS
DROP TABLE name [, ...] [ CASCADE | RESTRICT ]
INPUTS
name The name (optionally schema-qualified) of an existing
table to drop.
CASCADE
Automatically drop objects that depend on the table
(such as views).
RESTRICT
Refuse to drop the table if there are any dependent
objects. This is the default.
OUTPUTS
DROP TABLE
The message returned if the command completes
successfully.
ERROR: table "name" does not exist

DESCRIPTION
DROP TABLE removes tables from the database. Only its owner
may destroy a table. A table may be emptied of rows, but not
destroyed, by using DELETE.
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 foreign-key constraint
of another table, CASCADE must be specified. (CASCADE will
remove the foreign-key constraint, not the other table
itself.)
NOTES
Refer to CREATE TABLE and ALTER TABLE for information on how
to create or modify tables.
USAGE
