All files in src/common should be using the coding pattern

#ifndef FRONTEND
#include "postgres.h"
#else
#include "postgres_fe.h"
#endif

and as noted, it's going to take additional refactoring to make it
possible to do that in pg_lzcompress.  In view of all the potentially
unportable stuff Andres committed today, we need the buildfarm to be
at full strength; so I've reverted this commit until it can be worked
out a bit better.
