     Type:  defect          |     Status:  new
 Priority:  medium          |  Milestone:  PostGIS 3.6.0
Component:  tiger geocoder  |    Version:  master
 Keywords:                  |
----------------------------+---------------------------
 Right now tiger geocoder is using constraints.

 going to change this as part of the schema qualify work to use typmod.

 This should improve performance of geometry_columns and correctly show the
 types even though we are ripping out constraint support in
 geometry_columns in 3.6.
