1. libpq.so

   I suppose this is actually an OpenGroupware question, but nothing
   at that site seems to adequately address the issue.
   
   I run Debian, and it kind of looks like the debs at ogo.org are
   set for stable and I run unstable.  So, it really didn't surprise
   me when I see errors about not being able to find libpq.so.2.  The
   libpq on my machine is libpq.so.3; it being more up to date.
   
   The most verbose solution I've seen, is to "copy" libpq.so.3 to
   libpq.so.2 so that ogo will find a libpq.so library.  I would
   guess a symbolic link would actually be better, but the question I
   have is:
    Do all of the functions common to libpq.so in version 2 and 3
    have the same parameters?
   If not, I think this suggestion is nonsense, and I might as well
   just download source and compile it and give up on the debs at
   ogo.
   
   Thanks,
   Gord

   There are some incompatibilities (which is why we changed the major
   version number).  As best I recall at the moment, the incompatibilities
   would only affect applications that use LISTEN/NOTIFY, which not many
   do.  So the above would probably work, but it's not certain.

   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.
