For the query above, the following recommendations will be helpful as part of the SQL tuning process.

Description of the steps you can take to speed up the query.
The optimal indexes for this query, which you can copy and create in your database.
An automatically re-written query you can copy and execute in your database.

The optimization process and recommendations:

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 oat_tag_idx_user_tag_id_verifi_create_update ON "oat_user_tag_verification" ("user_id","tag_id","verification_status","created_at","updated_at");

The optimized query:

SELECT
        1 
    FROM
        oat.oat_user_tag_verification 
    WHERE
        outv.tag_id = f.tag_id 
        AND f.is_archived = false 
        AND oat_user_tag_verification.user_id = outv.user_id 
        AND oat_user_tag_verification.tag_id = outv.tag_id 
        AND oat_user_tag_verification.verification_status = outv.verification_status 
        AND oat_user_tag_verification.created_at = outv.created_at 
        AND oat_user_tag_verification.updated_at = outv.updated_at
