Introduce new patterns for direct sql that are safe and fast. MiniSql is not prone to memory bloat that can happen with direct PG usage. It also has an extremely fast materializer and very a convenient API - DB.exec(sql, *params) => runs sql returns row count - DB.query(sql, *params) => runs sql returns usable objects (not a hash) - DB.query_hash(sql, *params) => runs sql returns an array of hashes - DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array - DB.build(sql) => returns a sql builder See more at: https://github.com/discourse/mini_sql
