PostgreSQL version: 17.4
Operating system: Ubuntu 24.04 LTS ARM64 VM
Description:

In the debug build of PostgreSQL 17.4, compiled with `configure
--enable-debug --prefix=$(pwd) --exec-prefix=$(pwd) --enable-cassert`,
triggered Assertion Failure when executing the following statement:

```sql
SELECT ALL GROUP BY ALL ( ), CUBE ( CASE WHEN FALSE THEN TRUE END )
INTERSECT ALL SELECT ALL FROM JSON_ARRAY ( WITH any_cte_name AS ( ( TABLE
v00 ) ) VALUES ( FALSE ) ), any_table_name GROUP BY CUBE ( CASE WHEN TRUE
THEN FALSE END );
```

The assertion triggered is: Assert("IsA(cte->ctequery, InsertStmt) ||
IsA(cte->ctequery, UpdateStmt) || IsA(cte->ctequery, DeleteStmt) ||
IsA(cte->ctequery, MergeStmt)").
