QuerySet API - istartswith - use UPPER instead of ILIKE with PostgreSQL backend

QuerySet API - istartswith - use UPPER instead of ILIKE with PostgreSQL backend 

which conflict with Documentation (https://docs.djangoproject.com/en/dev/ref/models/querysets/)

as documentation's example shows SQL equivalent as " ILIKE "

Is this due to my backend being PostgreSQL? or is there setting that I can change?

I would like to know this so that we can strategize indexing of DB.

Any advice would be appreciated.
