Is there an easy way or a good practice to perform those type of tests in a production database?, for example adding index or the only way is cloning the db and test with it?

2:00 Once RANGE search is performed then the composite index stops there. So 'equals' search has to be placed first. Does Postgresql also behave the same way ?
