### Describe the Bug

I am attempting to set up drizzle with the schema from the Musicbrainz database. For reproduction purposes, this schema can be recreated by running [`mbslave`](https://github.com/acoustid/mbslave) with the command `mbslave init --create-user --create-database --empty`.

When pulling the schema from this database using `drizzle-kit pull`, I get a `schema.ts` with invalid syntax for default values. I've included the output for the first table below, but the output for all other tables is very similar:

```ts
export const alternativeMediumInMusicbrainz = musicbrainz.table("alternative_medium", {
id: integer().default(nextval('alternative_medium_id_seq'::regclass)).notNull(),
medium: integer().notNull(),
alternativeRelease: integer("alternative_release").notNull(),
name: varchar(),
}, (table) => [
check("alternative_medium_name_check", sql`((name)::text <> ''::text)`),]);
```

The desired result is that the `schema.ts` file is valid Typescript. In this case, I think omitting the default value altogether would be the best approach.
