perltidy PostgresNode and SimpleTee

Also, mention in README that Perl files should be perltidy'ed.  This
isn't really the best place (since we have Perl files elsewhere in the
tree) and this is already in pgindent's README, but this subdir is
likely to get hacked a whole lot more than the other Perl files, so it
seems okay to spend two lines on this.
