OK, I think we're getting somewhere.

I am still opposed to adding more targets of the form "light-install",
"client-only install", etc.  Please discuss this on -hackers.  It can
be done as a separate patch later on if need be.

While I now understand what you are doing in contrib, I ask who is going
to want to maintain two parallel sets of makefiles, one for PGXS and
one for in-tree builds?  One who is going to want to use the PGXS ones
anyway?  I realize they're good examples, but examples should be put
into the documentation, so people can find them.

Paste your documentation (pgxs.sgml) somewhere into xfunc.sgml, where it
discusses writing user-defined functions.  This material isn't long
enough to warrant a chapter of its own.

+ ifdef PGXS
+ LDFLAGS += -L$(pkglibdir)
+ endif

needs to disappear.  There is nothing to link with in there.  (If there
is, that's a bug.)

libpgport should be installed in the normal libdir.
