[Solved] PostgreSQL query and table structure improve performance

How to optimize this SQL query?

In case you have your own slow SQL query, you can optimize it automatically here.

For the query above, the following recommendations will be helpful as part of the SQL tuning process.
You'll find 3 sections below:

  1. Description of the steps you can take to speed up the query.
  2. The optimal indexes for this query, which you can copy and create in your database.
  3. An automatically re-written query you can copy and execute in your database.
The optimization process and recommendations:
  1. Create Optimal Indexes (modified query below): The recommended indexes are an integral part of this optimization effort and should be created before testing the execution duration of the optimized query.
Optimal indexes for this query:
CREATE INDEX daily_data_idx_id_pos_date ON "daily_data" ("id_pos","date");
CREATE INDEX daily_data_idx_id_pos_data_type ON "daily_data" ("id_pos","data_type");
The optimized query:
SELECT
        daily_data.id_pos,
        daily_data.data_type,
        sum(daily_data.value) AS data 
    FROM
        daily_data 
    WHERE
        daily_data.id_pos IN (
            1, 2
        ) 
        AND daily_data.date >= '2021-11-01' 
        AND daily_data.date <= '2021-11-30' 
    GROUP BY
        daily_data.id_pos,
        daily_data.data_type
