I am currently working with a Managed Instance from TimescaleDB and have incoming data. Now, I am setting up another instance, but this time it will be self-hosted and managed by me.

As such, I would like to setup some sort of replication so that the data coming into the managed instance is accessible in the self-hosted one (after a while, does not have to be live). I've looked into setting up replication with WAL streaming, however I've run into an issue.

Most replication workflows require changes in postgresql.conf and pg_hba.conf files which I cannot access (Managed instance). TimescaleDB support also says modifying this is not possible.

Is there a way to achieve this, without access to those files?
