osm2pgrouting | Import tool for OpenStreetMap data to pgRouting database | Map library

I'm working on a routing application using OSM data in pgrouting. I'm using overpass-api to access the data from a specific bounding box. However, after downloading the data, there seem to be tag_keys missing from the data.

When inspecting the data using postgis or QGIS, certain tag_keys are there, like "highway", "oneway" or "maxpeed". However, others seem to be missing. In particular the tag keys "bicycle" (with possible values like "yes" or "no") or "access" are not included in the data. These tag keys are available on OSM online, however.

The following code is used to retrieve the data from OSM through Overpass-API and put it into PGrouting

hellow, I'm learning to create a routing application with this new workshop. This is using Postgres as the database, and its extensions PostGIS and pgRouting. It uses GeoServer to manage data and publish that.

I got data from osm and then added it to database with osm2pgrouting to be able to use them. After that I installed geoserver too then created a layer for my data but when I try to create new SQL view I get this error:

ERROR: function wrk_fromatob(unknown, integer, integer, integer, integer) does not exist Hint: No function matches the given name and argument types. You might need to add explicit type casts. Position: 76

I searched a lot but I can't find any answer.

I would like to use one of pgrouting's algorithm to find the (shortest) path between 2 points with: (a) predominance for a specific type of road and (b) intemediate points.

To build the data I used the osm2pgrouting. I would like to focus first on the issue (a).

1. Is there an algorithm where I could define my preferences for the road type (in table ways class_id column class_id which represents road type or in table osm_way_types)?
2. If not how should I tweak my database? Knowing that I used the osm2pgrouting --> there is table public.osm_way_classes there is max_speed but it seems poor choice for tweaking it. I would like to leave it alone. I didn't really find anything useful in other tables. Any ideas?

Problem (b) (LESS IMPORTANT) is to determine if the length of searched path is less than for example 10km. If no then path should visit one of specified intermediate point (or points).
I don't think there are algorithms in pgrouting which condider these "stops" (intermediate points between source and target). I think this problem (b) should be solved by searching path from point1 to point2 and then from p2 to p3 etc. etc. but I don't know yet how to determine those points.

I need import open street maps data into my PostGIS database over osm2pgrouting tool. But when I run command, tables was created but without any data. Can you tell me what am I doing wrong? I have installed extension pgrouting in my db ...

As mapconfig I use default mapconfig.xml which is in same folder like osm2pgrouting tool (C:\Program Files\PostgreSQL\9.5\bin). I am using windows os.
