When creating indexes on the entity, we provide a basic query builder to generate
the SQL for where query upon the index. Since this is not a full query builder,
the onus is upon the user to ensure that the SQL is accurately generated.
Examples:
{ where: { column: null } }
{ where: { column: { $ne: null } } }
{ where: { boolean_column: true } }
{ where: { column: "value", another_column: { $ne: 30 }, boolean_column: true } }
