Extend the database initialization script to create a GiST (Generalized Search Tree) index on the `geom` column of the `regions` table. This will optimize spatial queries on this column. Signed-off-by: Nikolay Martyanov <ohmspectator@gmail.com>
Add a new field `geom` of type GEOMETRY('MULTIPOLYGON', 4326) to the Region
model to store the geometry data.
