I have a git alias:

check-whitespace = !git diff-tree --check $(git hash-object -t tree
/dev/null) HEAD ${1:-$GIT_PREFIX}

Also, in Emacs I use

(global-whitespace-mode 1)
(setq whitespace-style
      '(face
        trailing empty indentation space-after-tab space-before-tab))

With source code other than PostgreSQL, this will occasionally result in
angry fruit salad.
