Spatial Engine Connection Failed error with ArcGIS

Question

I have a database on PostgreSQL 9.5 when I try to connect to the database in ArcGIS desktop I get this message in log:

CAN'T OPEN INSTANCE: sde:postgresql. Spatial Engine Connection Failed (-51)

After that I have an error:

ev.SQLstate = 42501 SDE DBMS Error: -25 ERROR: must be owner of database base ev.SQLstate = 42P01 SDE DBMS Error: -37 ERROR: relation "sde.sde_layers" does not exist LINE 1: select count(*) from sde.sde_layers

File pg_hba.conf changed and users have CONNECT privileges.

What is the problem?

I'm following Esri instruction.
