duplicate key value violates unique constraint "geometry_columns_pk

[GeoTimber]

Hello, when I update the mapping file (based on osm bright template) to add some features to a table that were not included previously imposm crashed when i reimport the OSM PBF. Just after the vacuum analyze it dumps me:

Vacuum analyze

psycopg2.IntegrityError: duplicate key value violates unique constraint "geometry_columns_pk"
DETAIL: Key (f_table_catalog, f_table_schema, f_table_name, f_geometry_column)=(, public, osm_old_roads, geometry) already exists.

Something to do with the osm_old_roads already being there, any tips, can I just delete something here before I run imposm again?

Thanks anyway Joris

okay

If I run
delete from geometry_columns where f_table_name LIKE 'osm_old%';

before reimporting it is all solved,

I think
imposm -U postgres -d ... --remove-backup-tables
forgets to delete the road* views

no idea where to add this to imposm itself , maybe someone wants to update imposm?
