Access to oracle partitioned tables returns wrong result

[qinghuiguo]

Hello!
When I query the Oracle partition table in the PG using oracle_fdw, I returned the wrong result.

In PG ,it returned the data of the full table.

select count(*) from TS_QUICK_INCREASE partition(SYS_P902);

In fact, it returned the full table data, I expect to return the data of the partition。
