Padají testy pro postgresql

Ahoj,
prosím vás můžete mi někdo poradit proč mi padají testy pro nette/database ? Respektive výsledky se zdají být dobré jen špatně seřazené v poli. Všechno to jsou testy pro postgresql. Předpokládám že to bude nějakou konfigurací postgresql, ale fakt nemám tušení.

OS: Ubuntu 14.04

postgresql: 9.4.10

php 5.6.29
