Hi,
beside the other comments, you may try to rework your query to reduce the OR clauses which rise the uncertainty for the planner.
e.g.:
SELECT
*
FROM
table_name
WHERE code_id IN ( 1, 2)
UNION
SELECT
*
FROM
table_name
WHERE (code_id = 3 AND created_date < now())
LIMIT 1

Subject: Index creation
hello people, I would like to create an index so that the query on here can use it,
SELECT
*
FROM
table_name
WHERE (code_id = 1
OR code_id = 2
OR (code_id = 3
AND created_date < now()))
please advise me on how I should create index. I created index on code_id but it's not being used
