   I think I've mentioned this before, but I have the following function
   for adapting emacs to the Postgres code-formatting conventions:
   
   ; Cmd to set tab stops &etc for working with PostgreSQL code
   (defun pgsql-mode ()
     "Set PostgreSQL C indenting conventions in current buffer."
     (interactive)
     (c-mode)				; ensure we're in electric-C mode
     (setq tab-width 4)
     (c-set-style "bsd")
     (c-set-offset 'case-label '+)
   )
   
   Currently I invoke this command by hand when looking at a Postgres file.
   I've been meaning to set up a load-time hook to invoke it automatically
   upon visiting a .c or .h file within my ~postgres directory tree, but
   haven't got round to that yet.
   
   As far as I've noticed, the only significant shortcoming of this mode
   definition is that it doesn't know that "foreach" should be treated as a
   block-beginning keyword.  This is also fixable with a little elisp
   hacking, but that hasn't got to the top of the to-do list either.  For
   now I just remember to manually unindent the "{" right below "foreach",
   and then it carries on correctly for the rest of the block.
   
   ObFlameBait: Personally I think we should switch over to standard
   8-column tabs, but Bruce is apparently still using some medieval editor
   in which physical tab widths dictate logical indent levels :-(

   Vadim is also in agreement on this.  Not many editors can handle
   cases where tab size is different from indent size.  Emacs obviously
   can, and Tom has enjoyed pointing out.  :-)
   
   I am willing to re-open the discussion if we people would prefer
   something else.

   Trying to redefine a tab to be 4 spaces is asking for trouble. How about
   making pgindent replace 8 spaces with a tab and 4 spaces with, well, 4
   spaces. This is how emacs handles bsd indent style if you don't change the
   tab sizes. And all other editors should be fine with this.
   
   Personally, I'm always in favour of using no tabs at all, because of this
   very problem, and just because they annoy me. But I tend to be alone with
   that position.

   No you are not :). Twenty odd years of software development have taught me
   to remove the tab key from my keyboard. Two spaces do the trick for me and
   try to avoid at all costs lines over 80 cols. (I use emacs in vi[per] mode),
   even on win98... Oh how I wish we were back in the days of TECO.

   TECO!  If you were to dig up a copy of the original manual for
   Dec's OS/8 TECO, you'd see a reference to me on the first page.  Not
   by name, but by organization, for having done the first version.
   
   Sheesh, those where old days.
   
   Anyway, I too avoid tabs.  Life's too short to figure out how to
   make all the tools I use tab the way I want them to.
