When using the override seed file, the code only updates SqlPaths but doesn't ensure that Seed.Enabled is set to true. If seeding is disabled in the config file, the override seed file won't be executed. Consider adding a line to enable seeding when an override file is provided.

The new --override-seed-file flag lacks test coverage. Consider adding tests to verify that the custom seed file is used correctly and that it's properly mutually exclusive with --no-seed.

Recreates the local Postgres container and applies all local migrations found in `supabase/migrations` directory. If test data is defined in `supabase/seed.sql`, it will be seeded after the migrations are run. Any other data or schema changes made during local development will be discarded.

Use the `--no-seed` flag to skip seeding entirely. Alternatively, use the `--override-seed-file` flag to specify a custom seed file path instead of the default `supabase/seed.sql`. This is useful when you want to reset with different initial data, such as an empty state with minimal setup.

When running db reset with `--linked` or `--db-url` flag, a SQL script is executed to identify and drop all user created entities in the remote database. Since Postgres roles are cluster level entities, any custom roles created through the dashboard or `supabase/roles.sql` will not be deleted by remote reset.
