ALTER AGGREGATE myavg(integer) RENAME TO my_average;

To change the owner of the aggregate function myavg for type integer to joe:

ALTER AGGREGATE myavg(integer) OWNER TO joe;

To move the aggregate function myavg for type integer into schema myschema:

ALTER AGGREGATE myavg(integer) SET SCHEMA myschema;
