I have a posts table, which has an array column like so:

ALTER TABLE posts
ADD tags varchar[] default array[]::varchar[];

I inserted the value into the column:

UPDATE posts
SET tags = ARRAY['Miscellaneous']
WHERE id = 'my-first-post';

Which appears fine, but whenever I SELECT * with @vercel/postgres:

export type BlogPost = {
  id: string;
  title: string;
  subtitle: string;
  content: string;
  views: number;
  tags: string[];
};
const { rows } = await sql<BlogPost>`SELECT * FROM posts`;

It gives the following output for rows:

[
  {
    title: 'My First Post',
    subtitle: 'This is my first blog post!',
    content: '## It is kinda quiet in here...\\nWhat is next?',
    views: 0,
    id: 'my-first-post',
    tags: '{Miscellaneous}'
  }
]

Is this intended? Is tags not meant to be a string[] as it technically is in the Postgres table? Should I use an ORM if I want type "coercion" like this?
