Function not_ilike 

pub fn not_ilike<'a, L, R>(left: L, pattern: R) -> SQL<'a, PostgresValue<'a>>
where
    L: ToSQL<'a, PostgresValue<'a>>,
    R: Into<PostgresValue<'a>>,

Case-insensitive NOT LIKE pattern matching (PostgreSQL-specific)

Example

use drizzle_postgres::expr::not_ilike;

let query = not_ilike(user.name, "%admin%");
// Generates: "name" NOT ILIKE '%admin%'
