geography: increase cost of _ST_Expand and _ST_DWithin
|Reported by:||robe||Owned by:||pramsey|
Right now ST_Expand has a cost of 1 and ST_DWithin has a cost of 100. We should probably increase the cost of ST_Expand to at least 100 (and I'd up ST_Dwithin) a smidgen like maybe 150.
Although I haven't seen it in the field - perhaps because I haven't been looking, but I think the same issue with geography index possibly not being used under some circumstances would happen similar to the #2895 case .
