Type safe SQL query builder

/**
 * A driver that does absolutely nothing.
 *
 * You can use this to create Kysely instances solely for building queries
 *
 * ### Examples
 *
 * This example creates a Kysely instance for building postgres queries:
 *
 * ```ts
 * import {
 *   DummyDriver,
 *   Kysely,
 *   PostgresAdapter,
 *   PostgresIntrospector,
 *   PostgresQueryCompiler
 * } from 'kysely'
 * import type { Database } from 'type-editor' // imaginary module
 *
 * const db = new Kysely<Database>({
 *   dialect: {
 *     createAdapter: () => new PostgresAdapter(),
 *     createDriver: () => new DummyDriver(),
 *     createIntrospector: (db: Kysely<any>) => new PostgresIntrospector(db),
 *     createQueryCompiler: () => new PostgresQueryCompiler(),
 *   },
 * })
 * ```
 *
 * You can use it to build a query and compile it to SQL but trying to
 * execute the query will throw an error.
 *
 * ```ts
 * const { sql } = db.selectFrom('person').selectAll().compile()
 * console.log(sql) // select * from "person"
 * ```
