How to: Schema migrations table
Dbmate stores a record of each applied migration in table named `schema_migrations`. This table will be created for you automatically if it does not already exist.

The table is very simple:

```sql
CREATE TABLE IF NOT EXISTS schema_migrations (
  version VARCHAR(255) PRIMARY KEY
)
```

You can customize the name of this table using the `--migrations-table` flag or `DBMATE_MIGRATIONS_TABLE` environment variable.
