PostgreSQL is case sensitive if identifiers are quoted, otherwise it
folds to lower case.
SELECT foo, FOo, Foo, fOO -- all fold down to "foo"
SELECT "foo", "FOo", "Foo", "fOO" -- are all different
Not sure why lower was chosen over upper, probably a legibility issue. I
might be mistaken but I think the standard calls for upper; personally I
like the current system.
