Yes, through the post_install() and post_remove() functions in the install script (sample at /usr/share/pacman/proto.install)

Not exactly what I meant.  That is still per package, and if I understand Don correctly it's the fact that _every_ Haskell package does the same thing in its post_{install,remove}() (rebuilding the Haddock index) that is bothering him.  What I so clumsily tried to ask was if pacman has a post-{install,remove} action that _isn't_ per package but rather per invocation of pacman.  In this example, it would be nice to rebuild the haddock index once rather than once per package.

What you're talking of is a general hook mechanism which is being considered for pacman as it would not only simplify this case, but also allow us to update man-db, update the icon cache and mime cache etc. automatically, after all the packages in a pacman transaction have finished installing. Some initial discussion on this has taken place [1] [2], but I don't think anything concrete has happened.
