[Solved] Getting data that is more then or equal to in Postgres SQL query

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 run_item_idx_completed_at_started_at ON "run_item" ("completed_at","started_at");
The optimized query:
SELECT
        run_item.id,
        (EXTRACT(epoch 
    FROM
        now()) - EXTRACT(epoch 
    FROM
        started_at)) completed_time 
    FROM
        run_item 
    WHERE
        run_item.started_at IS NOT NULL 
        AND run_item.completed_at IS NULL
