How in ElectricEel-24.10.x access postgres side container? for example in home assistant.
Since upgrade to 24.10 I lost way to access to postgres DB which is used by home assistant. Previously I was able to access it for example from other app with pgAdmin.
After upgrade most likely as changes in networking I lost way how to access side container from other containers.
Checked, and same is for new deployed application (so this is not problem after upgrade).
How to backup/restore content of DB? I’m not able to use pg_dump as I’m not able to run it in context of posgress as don’t know the password.
