## Creating a new migration file
1. `make new_migration NAME=add_columnA_to_table1`
- This will create a new timestamped migration file in `db/migrations`
1. Write the migration code in the created file, under the respective `goose` pragma
- Goose automatically runs each migration in a transaction; don't add `BEGIN` and `COMMIT` statements.
1. Core migrations should be committed in their `goose fix`ed form. To do this, run `make version_migrations` which
converts timestamped migrations to migrations versioned by an incremented integer.
