Not sure if anyone has come across this as it doesn't appear to have been mentioned on the lists. I have only just found it and haven't tested it out. Sony Pictures Imageworks have released some of their internal projects as opensource using the bsd license - opensource.imageworks.com is the home site but the code and most info is hosted at code.google.com One of these projects would be of interest to some pg admins - scala-migrations - http://code.google.com/p/scala-migrations/ From the site - <quote> Scala Migrations is a library to manage upgrades and rollbacks to database schemas. Migrations allow a source control system to manage together the database schema and the code using the schema. It is designed to allow multiple developers working on a project with a database backend to design schema modifications independently, apply the migrations to their local database for debugging and when complete, check them into a source control system to manage as one manages normal source code. Other developers then check out the new migrations and apply them to their local database. Finally, the migrations are used to migrate the production databases to the latest schema version. The Scala Migrations library is written in Scala and makes use of the clean Scala language to write easy to understand migrations, which are also written in Scala. Scala Migrations provides a database abstraction layer that allows migrations to target any supported database vendor. ... Scala Migrations currently supports Derby Oracle PostgreSQL Patches for other databases are welcome. </quote> -- Shane Ambler pgSQL (at) Sheeky (dot) Biz -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
