Why do you need to be concerned with database migrations? There's nothing wrong with the modules you chose. Set up the schema manually or bring in a separate module... likely just a go install for a binary that will have a CLI for you to do any db schema creation and migration work you need - outside of your code base.

There's absolutely no reason at all that you need a more feature rich module. If you wanted something that offered a little more try an ORM likely possibly gorm.

I'd honestly just get a database GUI tool (dbeaver is what I use) and create your schema there. How often is your schema going to change? How often will you undo schema changes? Probably not much. I wouldn't worry about a DB migrations solution yet. You likely won't get any value from one. Edumacation though...you could learn about how they work.
