DROP AGGREGATE name ( type ) [ CASCADE | RESTRICT ]
The name (optionally schema-qualified) of an existing aggregate function.
The input data type of the aggregate function, or * if the function accepts any input type. (Refer to the PostgreSQL User's Guide for further information about data types.)
Automatically drop objects that depend on the aggregate.
Refuse to drop the aggregate if there are any dependent objects. This is the default.
DROP AGGREGATE will delete an existing aggregate definition. To execute this command the current user must be the owner of the aggregate.
Use CREATE AGGREGATE to create aggregate functions.
