[postgis-devel] Execution Cost

[Obe, Regina]

We should think about it.  For B) geometry functions should in general
have higher cost.  So I think a cost of 100 is better than 1.

Subject: [postgis-devel] Execution Cost

(a) Should we be looking at setting explicit costs onto our functions
as part of the 1.4 release?
(b) By defining our (ST_Intersects, etc) wrappers as 'SQL' language
have we harmed our helped ourselves? (Non-C functions are given
autocost of 100, C functions get autocost of 1.)
