> I'm surprised such a library ever got popular.

Because it is not popular.

pg_query (TFA) has ~1 million downloads, the postgres crate has 11 million downloads and the related tokio-postgres crate has over 33 million downloads. The two postgres crates currently see around 50x as much traffic as the (special-purpose) crate from the article.

edit: There is also pq-sys with over 12 million downloads, used by diesel, and sqlx-postgres with over 16 million downloads, used by sqlx.

Notably though, I believe neither tokio nor tokio-postgres parse SQL queries, they just pass them on the wire to the server. Generally the client side doesn't need to parse the query.

https://crates.io/crates/sqlparser has 48 million downloads, though. It's not exactly 100% compatible (yet!) but it's pretty darn great.
