Self Hosted Database ERD Manager? (lemmy.world)

Im looking for some form of self hosted application, ideally dockerized(able), that can connect to and manage an existing database (Im not picky on the DB type, Postgres prolly best though).

However Id like if it manages it via a nice well designed ERD. The closest I have found so far is PgAdmin but unfortunately it's ERD leaves a lot to be desired. It's kinda clunky, and it cant "diff" against your existing database to produce a migration script, all it can do is produce a script that expects you to totally drop the existing DB and re-apply the schema from scratch.

Something like Luna/Moon would be cool, but every example I look up seems to be an application you install locally on your machine and interact with directly, as opposed to a web interface.

If you know of such a tool let me know!

I do remember being a bit lost with initial connection to a postgres when I first spun up the app. I clicked around for a few minutes but after than it has been very handy. My use case was extremely basic as I just needed to manipulate some records that I did not know the right query for and to visualize the rows I needed.

I was able to connect to the DB with Cloudbeaver, but it straight up wasn't providing the diagram tab in the way the picture said it outta. The example pic even specifically is using a postgres DB as its example!

I pretty much had the exact same view, but no diagram tab. Unfortunately the wiki article doesn't go into much detail, it just says:

"(if the tab is not presented then the object does not support the diagram presentation)"

With no information provided further listing off what is, and is not, supported for diagram presentation.

Lack of documentation it seems, which is unfortunate. It seemed like it has potential but I spent a good 20 minutes fiddling with it, trying different configurations and settings, nothing made it start working and it seems like (as is the case on a few of these tools) the ERD tooling is often a bit of an afterthought and poorly supported.

Many of the tools are sql first, ERD... third? fourth? forgotten and lacking most features :(

Sad indeed. Maybe raising an issue on GitHub? Even if you don’t end up using cloudbeaver, it’s worth reporting it. Maybe they don’t know there’s a problem with this component of their app.
