>ALTER AGGREGATE</TT
> changes the definition of an
aggregate function.
</P
><P
> You must own the aggregate function to use <TT
CLASS="COMMAND"
>ALTER AGGREGATE</TT
>.
To change the schema of an aggregate function, you must also have
<TT
CLASS="LITERAL"
>CREATE</TT
> privilege on the new schema.
To alter the owner, you must also be a direct or indirect member of the new
owning role, and that role must have <TT
CLASS="LITERAL"
>CREATE</TT
> privilege on
the aggregate function's schema. (These restrictions enforce that altering
the owner doesn't do anything you couldn't do by dropping and recreating
the aggregate function. However, a superuser can alter ownership of any
aggregate function anyway.)
