Hi,
about database schema migrations:
I am very happy with south http://south.aeracode.org/
It is written for django (python web framework), but could be used for database
migrations outside django, too.

can anyone recommend an open source tool for diffing schemas?

We toyed with this exact issue at work. In the end, we went the other
direction, and created two files, both managed in source control: a
.sql file with everything necessary to initialize the database from
scratch, and a patch script. Every change gets done (by hand) to the
primary .sql file, and the SQL statements needed to effect the
transition (eg ALTER TABLE to add a column) get added to the patch
script. ...
