It'd be nice to have something more general - there are other perl modules we
load, e.g.
./src/backend/catalog/Catalog.pm
./src/backend/utils/mb/Unicode/convutils.pm
./src/tools/PerfectHash.pm

I think you got it, but just to make sure: I was thinking of generating a
depfile from within perl. Something like what you propose doesn't quite seems
like a sufficient improvement.

Yea. I'm working on a more complete version, also dealing with dependencies on
PerfectHash.pm.
