Mogdb/opengauss 分区表的一个分区 用什么方法能导出来?

例如

relname | parentid | parttype | partstrategy | interval | boundaries        

---------------+----------+----------+--------------+----------+-------------------------
 emp_range     |   349141 | r        | r            |          | 
 hiredate_1979 |   349141 | p        | r            |          | {"1980-01-01 00:00:00"}
 hiredate_1980 |   349141 | p        | r            |          | {"1981-01-01 00:00:00"}
 hiredate_1981 |   349141 | p        | r            |          | {"1982-01-01 00:00:00"}
 hiredate_1982 |   349141 | p        | r            |          | {"1983-01-01 00:00:00"}
 hiredate_1983 |   349141 | p        | r            |          | {"1984-01-01 00:00:00"}
 hiredate_1984 |   349141 | p        | r            |          | {"1985-01-01 00:00:00"}
 hiredate_1985 |   349141 | p        | r            |          | {"1986-01-01 00:00:00"}
 hiredate_1986 |   349141 | p        | r            |          | {"1987-01-01 00:00:00"}
 hiredate_1987 |   349141 | p        | r            |          | {"1988-01-01 00:00:00"}
 hiredate_max  |   349141 | p        | r            |          | {NULL}
(11 rows)
