I was always wondering if there is some way of database deployment which does not suck. And all I see - every professional team ends with bunch of 074-add-column-to-table.sql files. I mean, code deployment can be organized much better. You can make graceful restarts, transactional updates, etc. Actually, almost nobody backups old code version because deployment of new one may fail, but database upgrades are so fragile and making backups is a must not only because you afraid of upgrade process may be interrupted and leave database in inconsistent state, but because properly done upgrade may result in corrupted state.
