SQL: Create database automatically in dev mode if doesn't exist.

[r1tsuu]

(SQL only)
Create a database if it doesn't exist in the dev mode. Just like Prisma, MikroORM and others do.
Opt-out
To disable:

postgresAdapter({
  createDatabaseInDev: false
})

That would a bit improve the experience with spinning-up a new project / changing the DB

Actually why not in production too? Just thinking..
