Well, that's partially because right now it's really painful to do so,
and we've not tried to push people to do so. You essentially have to:
1) Pull down a new typedefs.list (how many people know where from?)
2) Add new typedefs that have been added in the commit-to-be
3) Run pgindent only on the changed files, because there's bound to be
thousands of unrelated reindents
4) Revert reindents in changed files that are unrelated to the commit.
1) is undocumented 2) is painful (add option to automatically
generate?), 3) is painful (add commandline tool?) 4) is painful. So
it's not particularly surprising that many don't bother.

Not sure how that invalidates my statement. If you have to script it
locally, and still have to add typedefs manually, that's still plenty
stuff every committer (and better even, ever contributor!) has to learn.

I wonder if we could add a command that pulls down an up2date list *and*
regenerates a list for the local tree with the local settings. And then
runs pgindent with the combined list - in most cases that'd result in a
properly indented tree. The number of commits with platform specific
changes that the author/committer doesn't compile/run isn't that high.
