 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
 .
