Many to many flatten response
I'm struggling to understand why does drizzle work this way and why there isnt an easy way to flatten the response structure. I have 3 tables, Profile, Interest and Language. I also have 2 other join tables, ProfileInterest and ProfileLanguage. As you may have noticed, I have a many-to-many relationship between Profile and Interest and between Profile and Language. All 5 tables are in place (3 "models" and 2 join tables). I also have all the relations created and everything works as expected. To query for a specific profile including its' interests and languages I run the following.
```
db.query.Profile.findFirst({
where: eq(Profile.id, input.id),...

How should I do custom migrations?
I am trying to do migrations in sqlite and sometimes drizzle will leave a comment in the migration file saying it cannot add constraints to existing columns, I understand it is necessary but it'd be appreciated if there was better documentation on how to achieve these things without leaving drizzle too much.
I feel like the whole migration process from drizzle-kit is not that clear and its quite hard to understand what are its limitations. For instance, I had a 0005_etc migration file written by me (I guess this is necessary to keep it version-controllable) and it used
BEGIN TRANSACTION;
Now, trying to run my 0006_etc file I am getting SQL_MANY_STATEMENTS and if I add statement-breakpoints I get SQLite error: cannot start a transaction within a transaction I am unsure about whether it has to do with this file or the previous one. Some of the questions that I am now getting:
- Does running drizzle-kit migrate run all files? how does it decide which to run?
- Why can't it point me to the file/statement that is erroring?...Switching between single and composite primary keys
I have resolved this by nuking my database and all migrations then recreating, but I ran into this error when changing the nature of primary keys. It also wouldn't let me remove the table by way of migration.

Correct way to instantiate a different client per environment?
I have a sst project which I also would like to run locally with a local postgresql connection and without instantiating a new AWS stack for it. This is my current approach, but I don't think it's great since the type of
db ends up being polymorphic.

How can I append a subquery as an array in the main query select? I'm currently using the alternative which is to use relational queries, but when using the

Automating migration
I am considering adding code to run a migration within my server startup. Basically, any time the server starts, the migration will run. The idea is that when the code is updated and the server restarts, the database stays up to date.
My questions: a) is there a way programmatically to determine if there is a need to do a migration? b) is there are a harm in running the migration every time you start up your server (
migrate(database, { migrationsFolder: './db/drizzle' });)...
