DROP TABLE — remove a table
DROP TABLE name [, ...] [ CASCADE | RESTRICT ]
DROP TABLE removes tables from the database.
Only its owner may destroy a table. To empty a table of rows,
without destroying the table, use 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 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.)
nameThe name (optionally schema-qualified) of the table to drop.
CASCADEAutomatically drop objects that depend on the table (such as views).
RESTRICTRefuse to drop the table if any objects depend on it. This is the default.
