Comment (by strk):

 The gitea PR (which includes upgrade tests) is green:
 https://git.osgeo.org/gitea/postgis/postgis/pulls/20
 GitLab PR is also green:
 https://gitlab.com/postgis/postgis/merge_requests/6

 Current state of branch is that on upgrade you get raster unpackaged and a
 WARNING message telling you to either repackage (if needed) or drop (if
 unneeded):
 {{{
 test=# alter extension postgis update;
 WARNING:  unpackaging raster
 WARNING:  PostGIS Raster functionality have been unpackaged
 HINT:  type `CREATE EXTENSION postgis_raster FROM unpackaged` to re-
 package or source `uninstall_rtpostgis.sql` to drop.
 WARNING:  'postgis.backend' is already set and cannot be changed until you
 reconnect
 ALTER EXTENSION
 }}}

 Regina suggested to directly drop the unpackaged raster but I'm not sure
 how we can tell if that support is still needed by the caller.
