Qlik Sense - Centralised logging has been disabled during the installation, but Windows Event logs report error FATAL: password authentication failed for user "qlogs_reader"

Centralised logging has been disabled during the installation of Qlik Sense, yet Windows Event logs report this error:

error FATAL: password authentication failed for user "qlogs_reader" DETAIL: Role "qlogs_reader" does not exist. Connection matched pg_hba.conf line 80: "host all all 127.0.0.1/32 md5"

SET db_v_file_override is set to 0
The License Monitor and Operations Monitor apps can read their logging data from two different sources,  the centralised logging database and the physical logs files.  However if you have disabled centralised logging an error is produced when the Apps try to access it first. You then see this error recorded in the Windows Event logs.

1. Firstly confirm in the QMC under tasks that your Reload License Monitor and Reload Operations Monitor tasks are reloading successfully with a status of "Success"
2. You will now need to duplicate and modify the License Monitor and Operations Monitor Apps. 
3. In the data reload script editor for each App, locate following setting:  SET db_v_file_override    =    0
4. Change this to SET db_v_file_override    =    1
5. Save the apps and republish over the old one.

This setting defines where the app reads its log data from.  The default is auto (0) and since you're just using "file logs only", you simply set this to 1 so it only tries to read from the log files,

        Old setting:
    SET db_v_file_override    =    0;

    New setting:
    SET db_v_file_override    =    1;

This is currently expected to be fixed in the June 18 release, but for now this is how you can resolve the logging error.
