Thanks Steve,
The actual fix for me was that I had to remove the "use" statement altogether. It was a schoolboy cut and paste error that it was in there in the first place. ![]()
However, I'm not sure I agree that it isn't a bug. The fact that liquibase reports "Successfully released change log lock" when blatantly no lock had been set on database_b, and the original lock is left in place on database_a surely isn't right?. However, I didn't just raise a Jira straight away, as I wanted to canvas opinions such as these first, thanks!
