It looks to me like section 34.10 of the docs might benefit from some sort of update in light of this patch, since the builtin array_agg now does the same thing as the proposed user-defined array_accum, only better. Presumably we should either pick a different example, or add a note that a builtin is available that does the same thing more efficiently.
