The index methods Postgres offers, for [ColumnIndexOptions.method](https://imqueue.org/api/pg-sequelize/latest/pg-sequelize.columnindexoptions.method/).

**Signature:**

```typescript
export declare enum IndexMethod 
```

## Enumeration Members


| Member | Value | Description |
| --- | --- | --- |
| BRIN | `"BRIN"` | Block range: huge tables whose values track their physical order. |
| BTREE | `"BTREE"` | Balanced tree: equality, ranges and ordering. Postgres's default. |
| GIN | `"GIN"` | Inverted index: containment in arrays, `jsonb` and full-text. |
| GIST | `"GIST"` | Generalised search tree: geometric types, ranges, full-text. |
| HASH | `"HASH"` | Hash: equality only, and smaller than a btree for that alone. |
| SPGIST | `"SPGIST"` | Space-partitioned GiST: quadtrees, tries and other unbalanced trees. |


## Remarks

Postgres uses `BTREE` when nothing is given, and it is the only method with an ordered key — so it is the one to want unless the data has a shape another method is built for.
