Documentation instructions for routing no longer work (pgrouting >=4) #408
Description
What version of PgOSM Flex are you using?
1.1.1
Docker image
1.1.1
What operating system, osm2pgsql, and PostgreSQL/PostGIS versions are you using?
Using Docker
What did you do exactly?
I was following the instructions for setting up routing here: https://pgosm-flex.com/routing.html and ran into the problem that all of the functions have been removed in version 4.0.0.
What did you expect to happen?
I expected the demo to work correctly.
What did happen instead?
Please see the error below:

SELECT pgr_createTopology('routing.road_line_noded', 0.1, 'geom');
SELECT pgr_analyzeGraph('routing.road_line_noded', 0.1, 'geom');

What did you do to try analyzing the problem?
I read the release notes and documentation of pgrouting. It looks like the workaround is a bit cumbersome, so I think the solution for me is to just downgrade to a version pgsom-flex that uses a version of pgrouting <4.
Do you have any plans to update the docs to work with the latest pgrouting version?
