DROP
NAME
DROP AGGREGATE - remove a user-defined aggregate function
SYNOPSIS
DROP AGGREGATE name ( type ) [ CASCADE | RESTRICT ]
INPUTS
name The name (optionally schema-qualified) of an existing aggregate
function.
type 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.) [Comment: This should become a
cross-reference rather than a hard-coded chapter number]
CASCADE
Automatically drop objects that depend on the aggregate.
RESTRICT
Refuse to drop the aggregate if there are any dependent objects. This
is the default.
OUTPUTS
DROP AGGREGATE
Message returned if the command is successful.
ERROR: RemoveAggregate: aggregate 'name' for type type does not exist
This message occurs if the aggregate function specified does not exist
in the database.
DESCRIPTION
DROP AGGREGATE will delete an existing aggregate definition. To execute
this command the current user must be the owner of the aggregate.
NOTES
Use CREATE AGGREGATE [create_aggregate(5)] to create aggregate functions.
USAGE
To remove the myavg aggregate for type int4:
DROP AGGREGATE myavg(int4);
COMPATIBILITY
SQL92
There is no DROP AGGREGATE statement in SQL92; the statement is a
PostgreSQL language extension.
