It may look like i forgot to do psql -d openstreetmap -c "CREATE EXTENSION btree_gist" command before start migrations, but it's not that.

Well you may have done that, but the database you are migrating is definitely missing the extension, so either you're not running against the database you think you are or something has removed it again, or recreated the database, since you ran that.
