* Windows 2016 server crashed after changes in Postgres 15.8 pgAdmin @ 2024-11-19 16:44 Sanjay Khatri <[email protected]> 0 siblings, 0 replies; 2+ messages in thread From: Sanjay Khatri @ 2024-11-19 16:44 UTC (permalink / raw) To: [email protected] Dear, Last week I installed Postgres 15.8 on my Windows server 2016, I installed the pgadmin thats comes packed with postgresql installer. I already have postgres 12.1 with pgAdmin installed on my server. After installing Postgres 15.8, the respective pgAdmin was not working, it showed error 'Postgres server could not be contacted' But the old pgAdmin(of Postgres12) was working fine, but was not displaying the postgres15 server on server list on pgAdmin. But, I wanted to work on the new pgAdmin (which was installed with postgres15). So I tried to find the solution on internet, and I got the solution. It was just to delete the pgAdmin.bak file from 'C\Users\Username\AppData\Roaming\pgAdmin\' And I did that and It worked, the bew PgAdmin started to work, it also displayed the Postgres15 connection se server list. But after 2 hours, my Windows Server 2016 crashed, and I am not able to boot my system. So on hard restart the system and it restarted well. And I quickly uninstalled the Postgres15 with its pgadmin from the machine. But the system crashed again after uninstalling the postgres 15. Now I am not able to boot the system. Its been 2 days the system is not able to boot. The system is on dell iDrac PowerEdge M6300. Is there any solution for this, I can try the solution if you suggest. We cannot format the Storage as our data is within the hardisk (Raid) type. And we dont have any data backup too. Please help if possible ^ permalink raw reply [nested|flat] 2+ messages in thread
