I’ve looked everywhere for this in NodeJS & adjacent stacks; almost all migration tools seem to focus on tables, columns and rows. None seem to deal with views, functions, triggers.

I only got back into Postgres this year, after almost a decade away from SQL. It’s kind of bizarre to me that the migration tooling is still at the stage where a 1 line change to eg a Postgres function requires a the whole function to be dropped and re-created?

I understand this is needed at the db level, but surely a “definition” that generates the final migration is doable; it would make such a huge difference in code reviews and to understand how a function/etc changed over time.

Am I just looking in the wrong place? Does this exist? If not, how come? Is it really that hard to do?

I believe Migra can generate those changes for you via diffing, not sure how well it handles dependent views/functions/etc

Thanks! I’ll give it a look (their docs are offline atm)

DrizzleKit and several others do this for table changes, but nothing I’ve found (possibly excluding Flyway and other Java options) do views/functions/etc.

The migra maintainer has abandoned it for greener pastures. If you’re interested in sponsoring an alternative, send me an email. My pgmigrate tool has all the groundwork necessary to make this possible but I have held off implementing this because I am not personally interested in using it.

Oh, that’s unfortunate.

I’m not too keen on sponsoring an alternative when the dev doesn’t particularly care about the feature — it didn’t work out last I tried something similar. But, perhaps there’s another path: Supabase.

They are in (imo) desperate need of better migration tooling, and they sponsor several open source projects that boost their over-all offering.

AFAIK, they haven’t done much in the migration space yet (aside from their alpha db branching feature), so I expect they’ll co-opt an open source solution at some point soon. May be worth pinging them? Seems it could be a win-win there.
