This sounds like a really good solution to me,
since there is actually nothing missing on the PostgreSQL server-side,
it's merely a matter of inconvenience on the client-side.

As long as the definitions of the database objects when stored
in the git repo can be written without the double-quotes,
i.e. CREATE TABLE Users (
instead of
CREATE TABLE "Users" (

where the object would be created as "Users" with capital "U",
then I see no problem.

Most people probably use psql to initiate a db instance of their
project locally,
so if psql would have a --preserve-case option, that would solve the
problem of creating new objects.
Or maybe --no-case-folding is a better name for the option.
