I have managed to connect to my OSM data using database connections in ArcGIS Desktop. I have the OSM line, point, polygon and roads tables. Now I am trying to query the tables using the Add New Query Layer.

I can load all data into ArcMap, but I would like to query the OSM tags. The column tags is currently a Unknown type. Therefore all my queries seems to fail.

Does anyone know how I should query the tags column here?

OSM tags are stored in an hstore column, a datatype not supported by ESRI. If you know the tags your are looking for you can create a view or a new table converting that key->value pair into column values. Here are some guides to help with that and to understand hstore better:
