@iNikitaGricenko Postgres tests are failing, can you have a look?

@iNikitaGricenko Vectorwize tests also fail, can you have a look?

[iNikitaGricenko]

@loicmathieu Could you help me with this one, please (Provide exceptions details or something)? As i didn't manage to download Actian Vector (Vectorwize)?

Just saw that Batch Vectorwise tests are disabled, I disable the two you added, CI should pass now (except Rockset but it's expected)
