A Postgres Service issue occurs when the database server cannot be started by Windows, or if the installation folder becomes corrupted. A Postgre SQL Database issue can occur if the database becomes corrupted.
Although database corruption is rare, it is typically caused by hard drive failure or by powering a computer down in the middle of a database function.
We do not advise uninstalling Postgre SQL unless you are having problems caused by the Postgres service, or if you intend to replace an old version of Postgre SQL with a newer major release without changing the ports used by the service.
You will see a response that says "The command completed successfully." If you do not see this message then Windows failed to delete the postgres service account user due to insufficient privileges.
If the computer clock loses time although you keep adjusting it, there may be a serious reason.
