Slony-I does not support versions of PostgreSQL earlier than 7.3.3.
As 7.3.2 is earlier than 7.3.3, I wouldn't expect that to work.

Yes, that would be right.

No, you cannot "skip" this. You _must_ submit slonik requests to add
each and every table that you wish to replicate to the replication
If there are 220 tables, you'll need something rather close to 220
"set add table" requests.

Maybe, depending on what you're trying to do.
