ALTER AGGREGATE OWNER seems to have been missed by the last couple of

patches that dealt with object ownership.  It wasn't updating pg_shdepend
nor adjusting the aggregate's ACL.  In 8.2 and up, fix this permanently
by making it use AlterFunctionOwner_oid.  In 8.1, the function code wasn't
factored that way, so just copy and paste.
