Suggestion: check out the Slonik library for Postgres. It encourages writing raw SQL using string template literals (i.e. sql`select foo from bar where zed = ${someParam}`). It also supports strong typing of results, but the programmer needs to create their own Zod validators manually to check this and get strong typing support.
Seems like this tool could essentially pre-create the types for any raw Postgres SQL statement?
I think this approach of using raw SQL is much better than a custom query builder like kysely, where half the time I'm just trying to translate the SQL that I know in my head to some custom, library-specific API. But the benefit of using kysely is the automatic typing support. Being able to use raw SQL and get query types "for free" would be amazing.
