No.
This has been discussed (many times) before. There isn't any feasible way to change this behavior without breaking an incredible amount of code, much of which isn't even under our control. The marginal increase in standards compliance is not worth the pain --- especially when the aspect of the standard in question isn't even one that most of us like. (All-upper-case is hard to read.)
If this is a deal-breaker for you, then I'm sorry, but you need to find another database. Postgres settled on this behavior fifteen years ago, and we're not changing it now.
Again my question was not to change the default behavior and make then All-upper-case as there is no need to change it.
Rather it was for alias names and if those are with upper case or mix case then wouldn't it will be good to preserve same. For me these changes to have aliases quoted are manageable and I was just checking for any thoughts here.
