Dynamic column selection with nested tagged string error

[lolgesten]

In issue https://github.com/porsager/postgres/issues/588 it says mixing string and tagged string as dynamic columns should work:

const columns = ['name', sql`ST_AsText(location) as loc_txt`];
const cities = await sql`SELECT ${sql(columns)} FROM city`;

However trying this locally, I get an error. As far as I can tell the function escape, str.replace expects only strings, where the tagged string is a Promise.

Is this a regression or intentional?

Seems like the same issue as #701. There's a workaround there you might find useful.
