Liquibase 3.3.2:
As you see, in the latter example it runs queries like "SHOW
FULL COLUMNS FROM `table1` FROM `test` LIKE '%'" for each
of the tables in the database. And in rainer.spruenkens case, this
will lead to the execution of 26.000 queries...
Liquibase 'updateTestingRollback' Successful Any ideas what the potential cause may be?

I am pretty sure its a classpath issue, but this occurs when running from within IntelliJ or on the commandline with gradle
How can we do that with Liquibase?
Using preconditions, I can do something to prevent ChangeSet 3 from running if ChangeSet 1 or 2 have already been applied. On the contrary, how could I prevent 1 and 2 from running (and let 3 run) when neither 1 nor 2 have been applied?
