emacs configuration for new perltidy settings

This might be useful for some people.  Here is an emacs configuration
for perl-mode that is compatible with the new perltidy settings.  Note
that the default perl-mode settings produce indentation that will be
completely shredded by the new perltidy settings.

(defun pgsql-perl-style ()
  "Perl style adjusted for PostgreSQL project"
  (interactive)
  (setq tab-width 4)
  (setq perl-indent-level 4)
  (setq perl-continued-statement-offset 4)
  (setq perl-continued-brace-offset 4)
  (setq perl-brace-offset 0)
  (setq perl-brace-imaginary-offset 0)
  (setq perl-label-offset -2))

(add-hook 'perl-mode-hook
           (lambda ()
             (if (string-match "postgresql" buffer-file-name)
                 (pgsql-perl-style))))
