Alias for table function in FROM clause is wrongly handled

[xxchan]

Describe the bug

It's changed from func_name.func_name to alias.alias

xxchan@/tmp:postgres>  select * from generate_series(1,2);
+-----------------+
| generate_series |
|-----------------|
| 1               |
| 2               |
+-----------------+
SELECT 2
Time: 0.007s
xxchan@/tmp:postgres>  select * from generate_series(1,2) a;
+---+
| a |
|---|
| 1 |
| 2 |
+---+
SELECT 2

In RisingWave, it's changed to alias.func_name

dev=> select a.range from range(1,2) as a;
 range
-------
     1
(1 row)
