Show HN: Postgres Language Server
fwiw, I personally am interested in this approach too[0]. I keep running into roadblocks around the ordering of events and some of the hairy issues around "destructive" actions (eg: renaming columns). i think we can get there, especially once we make progress with this LSP.

Quickly visualize your Django schemas with DjangoViz
My name is Rotem, I'm one of the creators of Atlas (https://atlasgo.io) a modern open-source schema management tool. Recently one of our engineers created a cool Django plugin that creates beautiful (in my eyes at least ;-)) and shareable ERDs from your Django data models.

Pgroll: zero-downtime, undoable, schema migrations for Postgres
Any pgroll operations[0] that require a change to an existing column, such as adding a constraint, will create a new copy of the column and backfill it using 'up' SQL defined in the migration and apply the change to that new column.
There are no operations that will modify the data of an existing column in-place, as this would violate the invariant that the old schema must remain usable alongside the new one.

Database Migrations
This is a fantastic article! It shows that even simple migrations (like adding or removing a column) can be quite tricky to deploy in concert with the application deployement.
We (at Xata) have tried for a while to come up with a generic schema migration system for PostgreSQL that makes this easier. We ended up using views and temporary columns in such a way that we can provide both the "old" and the "new" schema simultaneously. Up/down triggers convert newly inserted data from old to new and the other way around. This also has the advantage the it can do rollbacks instantly by just dropping the "new" view.
We were just planning to announce this as an open source project this week, but actually it is already public, so if you are curious: https://github.com/xataio/pgroll
