@tati-qalified could you please check if tableIsEmpty still works as expected?

Fix for the test failure https://github.com/liquibase/liquibase-pro-tests/pull/969 |

@rberezen the precondition is working as expected with an xml format changelog. I wasn't able to find how to implement the precondition for other formats, if it's even supported, so I didn't test those cases. |
