I'm of the contrary opinion.  A lot of the regular churn due to pgindent
right now is because it's inconvenient to run.  Having to clone a
separate repository, compile that project, put it into PATH (fun if
there's multiple versions), run pgindent, discover typedefs.list is out
of date, update, run, ...  is pretty much a guarantee that'll continue.
If we had a make indent that computed local typedefs list, *added* new
but not removed old ones, we could get much closer to just always being
properly indented.

The cost of putting it somewhere blow src/tools/pgindent seems fairly
minor.
