Are you just synching the schemas, or do you also need to synch the data?

Develop a function that builds a string describing the tables/schemas
you want to compare. Then have your function return the md5 sum of the
string as the result. This will give you a 32 character value you can
use to determine if there is a mismatch.

Schemas now, data later.

To do the data part, I'm thinking of using slony, because it seems to be able to
do pretty much everything I need from that side. But, unfortunately I can't
even start fixing the data before the schemas aren't fixed.

Kind Regards
