我已经被这个问题困扰了一个多星期了，我希望有人能在这里帮助我。
我正在运行带有 PostGIS 扩展的 Postgresql 12。我正在尝试使用 pg_upgrade 函数将数据库升级到 Postgresql 14。使用该--check选项运行时，结果显示“集群兼容”。
postgres@ual:~$ /usr/lib/postgresql/13/bin/pg_upgrade --old-datadir=/bnas/pgdata/postgresql/12/main --new-datadir=/bnas/pgdata/postgresql/13/main --old-bindir=/usr/lib/postgresql/12/bin --new-bindir=/usr/lib/postgresql/13/bin --old-options '-c config_file=/etc/postgresql/12/main/postgresql.conf' --new-options '-c config_file=/etc/postgresql/13/main/postgresql.conf' --check

但是，在没有--check执行实际更新选项的情况下运行时，它会在数据库的“创建数据库模式转储”处一直失败postgres。其他数据库的转储处理得很好。

Consult the last few lines of "pg_upgrade_dump_13427.log" for
the probable cause of the failure.
Failure, exiting
查阅“pg_upgrade_dump_13427.log”显示以下内容：

我之前按照本指南更新了 PostGIS 扩展，没有遇到任何错误。
PostGIS 更新是否破坏了postgres数据库？以前有人有过这种经历，有什么解决办法？请帮忙。
