upgrading from 6.10 2.2

When I upgrade my app to 7.2 at some stage the modeller needs to upgrade the database:

CREATE TABLE "mendixsystem$unique_constraint" (
    "name" varchar(255) NOT NULL,
    "table_id" varchar(36) NOT NULL,
    "column_id" varchar(36) NOT NULL,
    PRIMARY KEY("name","column_id"));

UPDATE "mendixsystem$version"
 SET "preanalysismigrationversionnumber" = '3.0.0';
 

After the start of the app I get the follwoing error when I use postgress Database, With build in database it runs without a problem.

Mendix.Modeler.M2EEConnector.M2EEException: The server encountered an error.

It seems there is some issue with postgress?
