### Apache Iceberg version
1.4.2
### Query engine
None
### Please describe the bug 🐞
We are using version 1.4.2 but we are planning to upgrade to 1.5.0 and I
confirmed that the problem is still there.
Problem: When you have 2 namespaces with similar names
E.g.:
namespaces:
- test.auto_rag
- test_auto_rag
API CALL: http://<iceberg-rest-catalog>/v1/namespaces?parent=test_auto_rag
Response:
```
{
"namespaces": [
[
"test",
"auto_rag"
]
]
}
```
That is incorrect. `test_auto_rag` namespace doesn't have children
namespaces.
In a quick look the issue seems to be with the behavior of this query with
postgres:
