It seems like Tomas gives you the solution (at least part of it): use
VACUUM FULL to compact your data on the master.
Also, probably you want to revisiti your autovacuum's configuration.
Finally, remember that Slony has two tables that logs all changes in
the database... normally only one of the table should be in use while
Slony is processing the queu of the other and truncate it. but if the
slon process are not running those tables start to grow... can you
check that the slon processes are running
