I don't think 7.4 had tablespaces (check the manual). In which case
you'll have to do it manually.
1. Stop the database server.
2. Create a new location for your db stuff /some/where/pgsql2/data/base
3. Move the directories you want over to the new location
4. Symlink each of the directories
cd /var/lib/pgsql/data/base
link -s /some/where/pgsql2/data/base/17142
5. Check ownership & permissions
6. Restart database
If you want to move all of them, rather than just individual databases
then you just need to move .../data and reset your PGDATA to point at
that. Can't remember where that gets set with the old RPMS - try in
/etc/postgresql or /etc/pgsql
