Data Incompleteness When Returned Rows Exceed rowsBatch(128)

[TianyuZhang1214]

When executing a query on any table with more than 128 rows, such as:

SELECT * FROM pg_class LIMIT 129;

The result is split into multiple segments, as shown below:

 oid  |                    relname                    | relnamespace | reltype | reloftype | relowner | relam | relfilenode | reltablespace | relpages | reltuples | relallvisible | reltoastrelid | relhasindex | relisshared | relpersistence | relkind | relnatts | relchecks | relhasrules | relhastriggers | relhassubclass | relrowsecurity | relforcerowsecurity | relispopulated | relreplident | relispartition | relrewrite | relfrozenxid | relminmxid | relacl | reloptions | relpartbound

(1 row)

This segmentation behavior disrupts the continuity of the result set, making it harder to process or view the data consistently.
