When -t is specified, pg_restore makes no attempt to dump any other database objects that the selected table(s) might depend upon.当指定 -t 时，pg_restore 不会尝试转储所选表可能依赖的任何其他数据库对象。 Therefore, there is no guarantee that the results of a specific-partitioned table dump can be successfully restored因此，不能保证特定分区表转储的结果可以成功恢复
However you can take dump using但是，您可以使用转储
pg_dump --host=hostname --username=user -t "child_table_*" --data-only --file=dump_out.sql dbname pg_dump --host=hostname --username=user -t "child_table_*" --data-only --file=dump_out.sql dbname
and then restore it, This is probably a consequence of the design decision to have partitions visible as individual tables on the SQL level.然后恢复它，这可能是设计决定将分区作为 SQL 级别上的单个表可见的结果。
