--------------------

- Create enum for 1d_advection_type and use use that for PhysicalSettings.use_advection_1d

--------------------

- Rename v2_1d_boundary_conditions and v2_2d_boundary_conditions to boundary_condition_1d and boundary_condition_2d.

- Rename v2_1d_laterals and v2_2d_laterals to lateral_1d and lateral_2d.

- Rename the_geom to geom in boundary_condition_2d and lateral_2d, and add geom columns to boundary_condition_1d and lateral_1d.

- Drop all constraints on boundary condition and lateral tables, except NOT NULL constrains on id and geom.

--------------------

- Prevent migration 222 to 224 from failing when any of the new table names already exists
- Swap start and end of control_measure_map geometries
- Modify geometry of controls associated with pumpstation to the pumpstation start node
- Ensure control_measure_map.geom is a valid line

--------------------

- Ensure dry_weather_flow_map.geom and surface_map.geom are valid lines

--------------------

- Do not migrate controls that refer to non-existing nodes

--------------------

- Use unique name for temp tables in migrations
