-## Index JSONB Columns for Efficient Querying
-
-JSONB queries without indexes scan the entire table. Use GIN indexes for containment queries.
-
-**Incorrect (no index on JSONB):**
-
-```sql
-create table products (
-  id bigint primary key,
-  attributes jsonb
-);
-
--- Full table scan for every query
-select * from products where attributes @> '{"color": "red"}';
-select * from products where attributes->>'brand' = 'Nike';
-```
-
-**Correct (GIN index for JSONB):**
-
-```sql
--- GIN index for containment operators (@>, ?, ?&, ?|)
-create index products_attrs_gin on products using gin (attributes);
-
--- Now containment queries use the index
-select * from products where attributes @> '{"color": "red"}';
-
--- For specific key lookups, use expression index
-create index products_brand_idx on products ((attributes->>'brand'));
-select * from products where attributes->>'brand' = 'Nike';
-```
-
-Choose the right operator class:
-
-```sql
--- jsonb_ops (default): supports all operators, larger index
-create index idx1 on products using gin (attributes);
-
--- jsonb_path_ops: only @> operator, but 2-3x smaller index
-create index idx2 on products using gin (attributes jsonb_path_ops);
-```
