Can psql on the linux connect to the postmaster on the sparc?
(If I am right about the postmaster supporting only unix domain sockets,
it should not.)

OK, you are dead in the water at this point...you can use only Unix domain
sockets and PoPy needs internet domain sockets.  (Unix domain sockets can
only talk when both client and server are on the same machine.)

It does matter for this reason:  libpq changed between the
6.3 series and the 6.5 series.  A client compiled against a
newer libpq cannot connect to a postmaster compiled against
the older libpq.  I know that the version distributed by mixadlive.com
was compiled with the new libpq.

My best guess:  you need to build new postgres on both machines.  For
locking performance, you certainly want a more recent version of postgres,
anyway!  The version you have almost certainly does table level locking.
You are going to have to rebuild the sparc's copy.  And dump and restore
may get to be 'interesting'.
