 Priority:  blocker         |  Milestone:  PostGIS 3.5.0
Component:  tiger geocoder  |    Version:  3.4.x
 Keywords:                  |
----------------------------+---------------------------
 Looks like tiger 2023 is out and they changed their naming structure, so
 probably more work to do than past years

 https://www2.census.gov/geo/tiger/TIGER_RD18/LAYER/

 I'm not exactly sure why the folder name is RD18 and why the change in
 files to be prefixed with tl_rd22 instead of just
 https://www2.census.gov/geo/tiger/TIGER2022/ (tl_)

 But anyrate I suspect things have changed enough that I might not be able
 to backport this to 3.4.1, and just slate this for 3.5.0.
