There are *NO* differences in the tables used.

Looking at the source tree for 1.2:
http://git.postgresql.org/gitweb?p=slony1-engine.git;a=tree;f=src/backend;h=03c8724fbb6e8574d56d58bdb3be54e4ad113f91;hb=refs/heads/REL_1_2_STABLE

The schema goes in slony1_base.sql.

While there are "version-specific" files  nominally for 7.3, 7.4, 8.0,
and 8.1, you'll find that these files are totally empty.

In contrast, there are material differences between the functions used,
where 7.3, 7.4, 8.0, 8.1, and 8.4 files contain not-huge but still
material bits of code that are loaded in by STORE NODE/UPDATE FUNCTIONS.

9.0 uses the same functions as 8.4, in that case.
