Yeah, I was kind of expecting some incompatibilities between
different major version numbers.  Which is why this advice on the
OpenGroupware forums seemed so strange.  But, I did set up the
symlink (libpq.so.2 -> libpq.so.3), and Open Groupware does at
least start.  I guess I'll exercise it a bit to see if anything
crashes it.
