[Alexander Kislitsky (akislitsky)]

When DB schema change is pushed to review, other tests are broken, until change is not merged into muster.

[Alexander Kislitsky (akislitsky)]

We can't drop and create DB from the tests. Let's make some workaround on the CI for this case.

[Igor Shishkin (teran)]

How it's going?
Why this bug is in progress still?

[Aleksandra Fedorova (bookwar)]

The problem described in this bug was fixed. I'll create new bug for general task of refactoring our postgres workflow
