我目前正在尝试在 2 个 GCP CloudSQL Postgres 实例之间设置pglogical复制，以便在区域之间快速迁移数据。
我按照 GCP 文档[1] 创建一个replicator用户，以该用户的身份安装pglogical扩展并执行所需的配置。
但是，每当我在目标服务上创建订阅时，状态最初变为initializing然后更改为down. Looking at thepostgres 日志，我可以在目标端看到以下错误：
db=api,user=replicator ERROR: permission denied for function pg_replication_origin_session_setup
我可以在目标数据库中看到提到的函数，但是每当我尝试GRANT EXECUTE使用它时，都会收到如下警告。
postgres=> \df+ pg_replication_origin_session_setup

有人曾经在 CloudSQL 上进行过设置吗pglogical？或者见过上述permission denied错误？
提前致谢。Gavin
