Create user Foo and Create user "Foo" are creating users with different
names. Since we want to allow both names to exist at the same time and for
you to refer to either, there needs to be a mechanism for doing so.  I
don't know about PHP, but as I said above, psql does not treat its
arguments as normal identifiers (thus lowercasing them) because it was
decided to be simpler for people to refer to either user.  For the former,
it is foo and the latter Foo.
