Do you have any public docs on how y'all migrate customers out of Heroku Postgres without downtime?
Seems to be the sticking point for a lot of people, myself included.

northflank supports the same buildpacks that you run on Heroku, so it should be fairly straightforward.
we have these docs for a more detailed walkthrough:

For a company like Northflank, I'd expect actual production-grade documentation for migrating, not instructions that are only applicable to a toy app.

Some folks want to do that, others want to import a backup directly, some want to spawn a read replica and sync their DB. Different strokes for different folks, all supported on Northflank.
I've had pretty good luck setting up logical replication from Heroku to the new provider and having a 10-15 minute maintenance window to catch up once it's in sync. Might be worth considering.
You might also want to add a warning about Postgres versions. There's some old bugs around primary key hash functions that can cause corruption on a migration. I've seen it twice when migrating from Heroku to other vendors.
