Well the problem is that it actually points to a current PGDATA just

In the pgsql_old installation you have symlinks pointing back to the
current default location. As well pg_tablespace points back to
/usr/local/pgsql/data/ The issue is that there is not actually
anything there in the way of a tablespace. So when pg_upgrade runs
it tries to upgrade from /usr/local/pgsql/data/tblspc_dir to
/usr/local/pgsql/data/tblspc_dir where the first directory either
does not exist. or if the user went ahead and created the directory
in the new installation, is empty. What is really wanted is to
upgrade from /usr/local/pgsql_old/data/tblspc_dir to
/usr/local/pgsql/data/tblspc_dir. Right now the only way that
happens is with user intervention.
Right, it points to _nothing_ in the _new_ cluster. Perhaps the
simplest approach would be to check all the pg_tablespace locations to
see if they point at real directories. If not, we would have to have
the user update pg_tablespace and the symlinks. :-( Actually, even in
9.2+, those symlinks are going to point at the same "nothing". That
would support checking the symlinks in all versions.
