Does PGPainless return exception as IOException? it would be better to have a predefined exception here. For now, it looks a little ugly

[DenBond7]

@IvanPizhenko it seems JUnit tests were broken. Please look at them.

[IvanPizhenko]

@DenBond7 thanks for noting this, will have a look.

[IvanPizhenko]

@DenBond7 that's new issue arised as result of changes in the PGPainless which we asked for, see more details in this comment #1347 (comment)

The fact our tests discovered this means they are pretty good - well done with the tests on this repo.

[IvanPizhenko]

@DenBond7 I think I've got it working, please recheck.

[DenBond7]

@DenBond7 I can't get "Instrumentation tests(with email server)" pass in CI. Rerun few times with no luck. This is not first time that it happens. Any ideas how to solve/improve this?
