I do this too.

As long as the app hasn’t shipped yet I just keep around a single migration file and I change it around as needed.

Another thing you might want to set up is a way to generate fake data for development. Then you can drop the db → run your single master migration file → generate new fake data in about 3 seconds once you get used to running the combo.

I guess I have to learn more psql commands…

Please, by any chance is there a way I can convert an Ecto migration file to pure psql command that I can paste in the psql console and execute it?

Edit: I mean I find it really easier to write Ecto queries instead of PostgreSQL ones.

If you have queries that you need more often than once, wrap them in a mix task, if it’s one off queries, do them on iex.
