Re: Deploying Odoo on 2 servers

this does highly depend on your Odoo use case. In my case i had a very large customer base (over 2 millions res_partner entries). So i had to add Trigram Indexes on the name field in res_partner.

But i also have changed the partners a little bit, they now have first name and last name - name gets computed. Also have divided street into streetname and house number.

So Indexes are really very depended on use case. Best thing is to let postgresql log all queries which takes longer than xx seconds - then inspect the log file - and try to optimize the database.

Have the indexes created in the standard will be not that easy, Trigram indexes are an extension to postgres as far as i know..

Would you care to name some of the fields which benefit most from this 
kind of index ?
Probably we could make a PR to have them created in the standard.
