Can you please point out the solution to the problem?
I can see the solution in the link:
Search for all Configure-Service.ps1 files in C:\program files\qlik\sense
replace the line
[string]$postgresHome = "$senseInstallPath\Repository\PostgreSQL\9.6",
[string]$postgresHome = "$senseInstallPath\Repository\PostgreSQL\12.5",
after that reset the passwords once more for all the Micro Services and restart the Qlik Sense Services under services.msc
But I can see postgres version is already 12.5 in my configuration.
