Interesting. I test this on Postgres, it returned 5 rows too if disable
using indexes including bitmap.
```sql
explain SELECT * FROM point_tbl WHERE f1 <@ polygon
'(0,0),(0,100),(100,100),(50,50),(100,0),(0,0)';
QUERY PLAN
----------------------------------------------------------------------------------
Index Only Scan using gpointind on point_tbl (cost=0.13..8.15 rows=1
width=16)
Index Cond: (f1 <@
'((0,0),(0,100),(100,100),(50,50),(100,0),(0,0))'::polygon)
(2 rows)
SELECT * FROM point_tbl WHERE f1 <@ polygon
'(0,0),(0,100),(100,100),(50,50),(100,0),(0,0)';
f1
