我有一个Azure Postgres灵活服务器正在运行，需要备份其中的数据库
按照Postgres文档9.1.4中的说明在这里
我精心制作了下面的pg-dump命令。

pg_dump -b -Z0 -F t --host=hidden --username=hidden --dbname=temp --file=backup.tar

字符串
它会运行几个小时，然后失败，输出如下

pg_dump: error: error reading large object 350828: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

型
任何帮助弄清楚这一点将不胜感激
