I think the fact that aggregates have a separate command is somewhat
historical. However, the fact remains that at the SQL level there is
CREATE/DROP/etc AGGREGATE and CREATE/DROP/etc FUNCTION, and nothing
else. If we don't hang psql's hat on that same hook then we are going
to confuse users --- not to mention that this thread will never reach a
resolution because there will be too many alternatives.
