I want to draw peoples attention to

The HAVE_PGPORT on windows doesn't seem to work when I recently tested 
against PG12.

I am also not sure this is working on unix against recent PG versions(do 
--have-pgport builds work for anyone else).

Since we now have runtime facilities to set the sharepath with 
SLONY_SHARE_DIR I think removing this is fine.

My plan is to release 2.2.8 from REL_2_2_STABLE this coming weekend or early 
next week.  If anyone objects to this release schedule or the PGPORT change 
let me know.

I suspect we should pull out all the HAVE_PGPORT blocks but I won't do that 
in 2.2.8.  Windows packagers could just add back the define if I'm wrong 
about this issue.
