When using PostrgeSQL an InternalError is raised by the db when these subsequent commands are attempted as PostgreSQL disallows this behaviour. MySQL and SQLite3 are less strict and so no error is raised, leading to confusing and hard to diagnose behaviour. The current documentation doesn't highlight this potential pitfall.",Cleanup/optimization,closed,"Database layer (models, ORM)",1.6-beta-1,Release blocker,fixed,,,Ready for checkin,1,0,0,0,0,0
