     * Creates or updates the entity, based on whether it is already present in the database.
     * This method performs an `insert on conflict merge` query ensuring the database is in sync, returning a managed
     * entity instance. The method accepts either `entityName` together with the entity `data`, or just entity instance.
     *
     * ```ts
     * // insert into "author" ("age", "email") values (33, 'foo@bar.com') on conflict ("email") do update set "age" = 41
     * const author = await em.getRepository(Author).upsert({ email: 'foo@bar.com', age: 33 });

     * // insert into "author" ("age", "email") values (33, 'foo@bar.com') on conflict ("email") do update set "age" = 41

     * const author = await em.getRepository(Author).upsert({ email: 'foo@bar.com', age: 33 });
     * ```
     *
     * Depending on the driver support, this will either use a returning query, or a separate select query, to fetch the primary key if it's missing from the `data`.
     *
     * If the entity is already present in current context, there won't be any queries - instead, the entity data will be assigned and an explicit `flush` will be required for those changes to be persisted.
