My .vim. Probably not interesting to anyone but me, except that I have a custom pgsql.vim for highlighting PostgreSQL which I think is much better than any other I've seen out there, though I admit it is not perfect. It does syntax highlighting for PLPGSQL inside function definitions as long as $$ is used as the delimiter. It started with Devrim Gunduz' pgsql.vim, but not much of that remains. It has been almost completely reworked.
Note that I started with Derek Wyatt's vim config and went from there.
