Thanks for the reply Vladimir,

I thought explain analyze is enough. I run vacuum analyze manually but it didn't work either.

Yavuz, cannot add much to other points but as for index-only scan, an (auto)vacuum must be run in order to optimizer understand it can utilize index-only scan. Please check if autovacuum was run on the table after index creation and if no, run it manually.
