Only the table owner, the schema owner, and superuser can drop a table.

However, to drop a table that is referenced by a view or a foreign-key constraint of another table, <TT CLASS="LITERAL" >CASCADE</TT > must be specified. (<TT CLASS="LITERAL" >CASCADE</TT > 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.) </P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN74640" ></A ><H2 >Parameters</H2 ><P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT ><TT CLASS="LITERAL" >IF EXISTS</TT ></DT ><DD ><P > Do not throw an error if the table does not exist.
