### Partitioned Table ONLINE Index Build

Source: https://docs.ivorysql.org/cn/ivorysql-doc/master/oracle_compatibility/compat_create_index_online

Shows how to create an ONLINE index on a partitioned table, noting that it silently degrades to a regular build. Verifies index validity across parent and partitions.

```sql
-- 分区表父级索引 ONLINE
-- 注：ONLINE 在分区表上静默降级为普通构建，与 Oracle 行为一致
CREATE INDEX idx_part_online ON tbl_ci_part (id) ONLINE;

-- 验证索引已创建且有效（降级为普通构建，父级索引 + 各分区子索引均 VALID）
SELECT c.relname, i.indisvalid
FROM pg_index i
JOIN pg_class c ON c.oid = i.indexrelid
WHERE c.relname LIKE '%idx_part_online%'
ORDER BY c.relname;
-- 期望：idx_part_online（父）及两个分区子索引 indisvalid = t

-- 分区表 ONLINE + TABLESPACE
CREATE INDEX idx_part_online_tbs ON tbl_ci_part (region) ONLINE TABLESPACE pg_default;
```
