Comment(by dbaston):

 Hi robe,

 I agree, and I think the simplicity benefits of defining aggregates is
 worth it in this case.  I like the idea of also providing standard
 functions that accept geometry[], so I've added those into this version.

 I also updated the pull request this evening to include
 ST_ClusterWithin().  One aspect I hadn't anticipated was the need to
 update pgis_abs to carry along a Datum (like distance tolerance in this
 case) to the finalizing function.  Let me know if there is a better way to
 do this.  (I couldn't find anything except maybe some new syntax for 9.4).
