The preferred contents of probin are now like
$libdir/plpgsql
(the dollar sign is literal text here). As of 7.2 the server will
substitute a suitable directory name for "$libdir". You probably
have a database that was reloaded from an old dump without taking
advantage of this feature --- before 7.2 you could only use an
absolute path in probin. Now, absolute paths are deprecated for exactly
the reason that they make version updates hard.
Note the lack of a ".so" in that probin entry, too. This is also
a recommended new practice in 7.2 --- no reason to put
platform-dependent assumptions about shared library extensions into
your dumps.
