Well, that would depend. If you were building from a distribution
tarball (which should contain src/backend/catalog/schemapg.h) then
yeah the symlink ought to point at it --- and it does, in my testing.
But if you were building out-of-tree from a bare git pull, then
src/backend/catalog/schemapg.h would be created in the build tree,
and that's where the symlink would point.

I can imagine breaking that logic if you got sufficiently creative
about switching between in-tree and out-of-tree builds and not
reconfiguring the build tree between uses ... but all the ordinary
cases work fine as far as I can tell.
