Filling the indent area with dots is not a sensible default IMO. Often when I work on a query I am going to reuse it in an application. If PgAdmin III or psql filled the indent area with dots then they would be included when I copied the query I'd written.
Even though I always reformat the query, and even though the text editor I use -- vim / neo-vim -- supports rectangular text selection, I would be annoyed at such dots.
