Symptoms

• We connected to PostgreSQL and created a Database. When trying to connect to any FlxiCapture 12 station received an error message None of the stations are available:
  You do not have permissions to access any of the stations.
  You can create a request to get these permissions from the administrator.
• The "Principle" table is not updated after the Database creation screen in the Database. 
• "issystemadministrator"  (boolean) was set to "false".

Cause

This situation regarding set-up permissions. It could be fixed by adding a permission role to your account manually. 

Resolution

There are two ways how to resolve this issue:

1. Using Administration and Monitoring Console;
2. In Database.

If you are able to log into the Administration and Monitoring Console with any of the users, be it a default user or WinAuth login, to add the Administrator role to the needed users to which the access was not added initially:

Open Console > Settings > Users > Select the needed user > Select Administrator role:

The second solution:

Please log into your created Database using the program of choice. There should be two tables we need: 
"Principal" and "PrincipalPermission".

1. Inside "Principal", find the user under which you are logging in and copy the PrincipalID field value. 
2. Inside "PrincipalPermission", add a new record for the needed role. Set the IsAllowed=True. In this case, the Administrator has RoleID=10.
