Database error, [Backend] Default PostgreSQLserver cannot start. PostgresqlServer
Posted: Wed Apr 16, 2025 3:48 pm
Now I use WinCC OA 3.20 P004 in Windows 11 Pro.
When I start the project, there is an error in the logviewer:
Database error, [Backend] Default PostgreSQLserver cannot start. PostgresqlServer::startCommand: process crashed command(pg_ctl status -D C:\NTU\db\wincc_oa\localdb\postgresql\16\pgdata) (from System1:_NGA_B_PostgreSQLBackend)
I have ensured the user has full control privileges of the project folder. (It works when the project runs in Windows Server 2022 STD)
But the problem still can not be solved in Windows 11 Pro.
Is there any thing I can do?
