It looks like the problem is that there aren't any Postgres-specific -I
flags in the make command. After a bit of poking around in the pgxs code
I think the reason why not is that you're using the PROGRAM target instead
of MODULES or MODULE_big. This might be a bug in our makefiles, but it's
also somewhat defensible, in that if you're building a standalone program
then you aren't going to have access to any server internal functions.
What's your actual goal here --- are you trying to build a server
extension or a standalone program? If the former, you should be using the
MODULES or MODULE_big targets. If the latter, you should probably be
including postgres_fe.h not postgres.h.

Since you let slip that you're using ubuntu, they probably have names
ending in -dev not -devel.
