yes, both type and "lt" is supported.  I sent a mail about the
module API to slony1-hackers where you can get the overview:

I think it would be really good if we could settle on single
module.  That makes getting it into core quite likely, especially
considering that it's useful not only for replication, but for
anybody who wants to implement queue-like things in database.

Not too soon but not too far off too.

Main change would be to replace the 4-byte xxid with 8-byte bigint
type.  Does not sound very bad, but I'm not familiar with SlonyI
code, you need to decide for yourself.
