 * milestone:  PostGIS 3.5.0 => PostGIS 3.4.1

Comment:

 Okay this is not as much of a change as I feared.  Seems changing
 loader_variables table is sufficient to make this work


 {{{
 UPDATE loader_variables tiger_year = 'rd22', website_root =
 'https://www2.census.gov/geo/tiger/TIGER_RD18/LAYER';
 }}}

 is sufficient to make it work.  That said I think I can backport this to
 3.4.1 without issue.

 I'm doing some tests on demo.postgis.net  I have tiger_2022 loaded, not
 loading tiger_2023 with the changes to see if any issues before I push
 these.

 So far so good. DC seems to have loaded fine and in middle of loading MA.

 I guess Connecticut underwent some changes.  We have one county less and 8
 new Connecticut counties not in 2022 set.
