Yeah, this isn't going to happen.  Years ago we looked into what it would

pain points even in terms of server-side implementation, never mind all
the applications we'd break.

Alright, thanks to everyone for looking into this. Not knowing the code, I naively assumed it should be easy to add an option to not do the case folding.
 

What the OP is asking for doesn't even have the argument "but it's
standards compliant!" going for it. 

Indeed, my argument was it would allow people to choose their own naming convention to (easily) use with Postgres, which would in turn make it easier to migrate from other RDBMSes to Postgres. Although, if you want a standard compliance argument, that can easily be added. :) Just have 3 options: fold to lowercase (current behaviour, default), fold to uppercase (standards compliant), do not fold (most flexible, compatible with MSSQL and MySQL).

Well, I was going to ask if paying someone to fix this was an option, but this preempts that!
