This PR addresses two main issues introduced by the new ID-Based Merged-LineString Updates
1. Partial Indexes can only be accessed when the query matches more or less exactly and the query-planner will fail to use indexes when targeted via the join-condition and not the where-condition
- `osm_transportation_merge_linestring_gen_z9`
- `osm_transportation_name_network`
- `osm_shipway_linestring`
- `osm_aerialway_linestring`
- `osm_waterway_linestring`
2. When intersecting updated Source-LineStrings with the existing Merged-LineStrings we join the Source-IDs of each existing Merged-LineString. This bloats the table unnecessarily and slows down bigger updates considerably.
- This is addressed by aggregating the Source-IDs of each existing Merged-LineString into an array and concatinating these arrays when grouping them. Afterwards we add the IDs of updated SourceLineStrings and deduplicate the result before adding it to the Source-IDs-Table.
