What is PQ good for?

[novellizator]

So I usually run stuff like this:

await db.map(query, [param1])

Where the query can either be a string or a PQ . What are the advantages of using PQ?
The disadvantages are clear, for example if the query in PQ contains $1:list I get a syntax error. Can I drop PQ() from the whole codebase without any disadvantage? What should I look out for?

Prepared Queries are formatted on the server side. And they can be additionally optimized for performance, i.e. SQL execution plan is cached.
