can anyone recommend an open source tool for diffing schemas?
(it should go without saying that i'm looking for ddl to update production and QA DBs from development DBs, but i'll say it, just in case.)

Richard,
Usage is something like this ...
c:> java -jar apgdiff.jar --ignore-start-with pg_old.sql pg_new.sql > diff.sql
It is PostgreSQL specific. Takes two SQL files and produces the diff.sql, that we use as the basis of our production upgrade artifacts.
A very useful and basic tool..
