Hi,
I have this query:
select * from reo inner join usr on reo.owner_id=usr.user_id
I also have created these indexes:
CREATE INDEX "owner_id_reo_key" ON reo (owner_id);
CREATE INDEX "user_id_user_key" ON usr (user_id);
Explain tells me this:
Merge Join (cost=1341.74..1481.12 rows=299697 width=461)
-> Sort (cost=775.05..775.05 rows=6629 width=328)
-> Seq Scan on apartment_reo reo (cost=0.00..354.29 rows=6629
width=328)
-> Sort (cost=566.69..566.69 rows=4521 width=133)
-> Seq Scan on USER usr (cost=0.00..292.21 rows=4521 width=133)
Why it does not use indexes I have created?
