DROP TABLE(7)                    SQL Commands                    DROP TABLE(7)

       DROP TABLE - remove a table

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

       DROP TABLE removes tables from the database.  Only its owner can drop a table. To empty a table of rows without
       destroying the table, use DELETE [delete(7)] or TRUNCATE [truncate(7)].

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.   How-
       ever,  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.)

       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.

              Automatically drop objects that depend on the table (such as views).

              Refuse to drop the table if any objects depend on it. This is the default.

       To destroy two tables, films and distributors:

       DROP TABLE films, distributors;

       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.

       ALTER TABLE [alter_table(7)], CREATE TABLE [create_table(7)]
