Disclaimer: I've never used eclipse.

The problem is some perhaps-too-clever stuff we do to avoid repetitive
declarations of things.  The rmgr stuff uses a PG_RMGR macro, which is
defined differently in src/backend/access/transam/rmgr.c and
src/include/access/rmgr.h; the latter contains the actual enum
definition.  On the other hand Eclipse is trying to be too clever by
processing the C files, but not actually getting it completely right
(which is understandable, really).  We have other similar cases, such as
grammar keywords (kwlist.h)

I'm afraid that you'd have to teach Eclipse to deal with such things
(which might be tricky) or live with it.
