That is the case.  I tried switching it to postgres_fe.h, but then I got errors about the pg_type structure not being defined.  It appears that the CATALOG macro (which defines the structure) is defined in postgres.h but not in postgres_fe.h.  I don't see any other headers in src/ which do define it.

I worked around this by switching back to postgres.h, and #defining ELOG_H above postgres.h (to block elog.h).  Nonoptimal, but it gets the compile going again.

Thanks for the suggestion; knowing that elog.h was backend only gave me the courage to exclude it.
