Missing column junction in polygon-view

[rrzefox]

Current master will probably not work, because it needs a column 'junction' in the polygon-table - which the current view_polygon.sql does not set up.
It will probably need something like
tags->'junction' as "junction",
else it ends like this:
Postgis Plugin: ERROR: column "junction" does not exist#012LINE 14: junction,#012 ^#012HIN T: There is a column named "junction" in table "*SELECT* 1", but it cannot be referenced from this part of the query. [...] encountered during parsing of layer 'junctions' in Layer at line 51315
