#5259: PostGIS Functions over-costed
---------------------+---------------------------
 Reporter:  pramsey  |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  high     |  Milestone:  PostGIS 3.4.0
Component:  postgis  |    Version:  master

 In general, the high (and arbitrary) costs assigned to some PostGIS
 functions are flipping plans into less desirable states. On the repeatable
 case discussed, cutting the high cost in half allowed the preferred plan
 to prevail. In general we want to keep our function costs high, since
 compared to pretty much all PgSQL core functions we do have some extremely
 high computation needs, and want plans that reflect that.
