Only the table owner, the schema owner, and superuser can drop a table\&. To empty a table of rows without destroying the table, use +\fBDELETE\fR +or +\fBTRUNCATE\fR\&. +.PP +\fBDROP TABLE\fR +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\&.
