Hi All, We are thinking of putting our galaxy instance in a new more powerful environment. Galaxy is now on a single server containing a psql database which is migrated from mysql a few years ago. The new environment already houses a really nice backupped highly available mysql server. as galaxy admin I am quite reluctant of migrating back to mysql, the system admin is quite reluctant of installing this psql database with the same grade of backup and availability just for galaxy. I could only come up with the line "*PostgreSQL is much preferred since we've found it works better with our DB abstraction layer, SQLAlchemy <http://www.sqlalchemy.org/>.*" from the galaxy wiki, which is a rather slim argument. My question now is. Is Postgres still the preferred database or is Mysql now also a safe bet. For mysql we would have to migrate back, system management would have a lot of experience tuning databases and a high quality instance is already running. For Psql a new database instance would have to be installed, less knowledge of the database system is available but it is the preferred database. Could someone point out some more pros and cons in this question?
