Introduce compile-time SQL verification

[shah]

One interesting feature of sqlx is compile-time SQL verification without using a special DSL. We should either use that same approach for testing generating SQL against a real PostgreSQL or other enterprise database (like we do for SQLite) or we can see if sqlx crate can be used directly in Deno.

In addition check out tree-sitter with SQL grammar for tree-sitter.

We can also use sqlparser-rs (see Parsing SQL with Rust Reddit thread for other ideas).
