Hi Dave,

This isn't the issue in the case of sqlite db while using persistent storage. Issue appears only if external database is used as pgadmin configuration db. Just having different way of persistent storage( in this case backend database) behaviour should not be different. 

No, the two database types should behave the same way. Why then, is PostgreSQL different from SQLite? Is SQLIte effectively using the --replace option whilst PostgreSQL is not (though I can't imagine why that would be the case)?

Issue is because the loading server is performed in the absence of the  '/var/lib/pgadmin/pgadmin4.db'  file which is always true in case of an external database.

Ah, well in that case for PostgreSQL we can just check if the pgAdmin schema has all been created/loaded right?

 

However, I retract my previous comment (though if this were new behaviour, perhaps I wouldn't) - the docs say:

=====

If this file is mapped, server definitions found in it will be loaded at launch time. This allows connection information to be pre-loaded into the instance of pgAdmin in the container. Note that server definitions are only loaded on first launch, i.e. when the configuration database is created, and not on subsequent launches using the same configuration database.

=====

So the advertised feature is that we do only load the servers once into any given configuration database.

 

Also, on restart admin user specified while container is not recreated. Can't we fix on similar lines?

Hi Hackers,

I am working on issue #7811, where using an external database for storing pgAdmin configuration results in duplicate server entries when a container with a mapped servers.json file is restarted.

The proposed solution is to implement a check when loading servers. We would verify the server’s name, host, port, and username to determine if the server already exists in the database. If it does, we would skip registering it again.

Please share any suggestions or feedback on this approach.

I would say "Won't fix". If someone is using persistent storage for settings, why launch containers to import the same servers over and over again? Just load them once, manually. 

What if the container needs to be restarted? In that case it will again import the server making a duplicate entry.

Not if the servers are manually imported rather than through servers.json.
