Hello. I try to upgrade to the newest version 2.55+161021 from a 2.0 version with postgreSql. During the upgrade the following error is displayed:

Ein Fehler trat während des Datenbankupdates auf. Fehlerinformation:
CDbCommand konnte das SQL-Statement nicht ausführen: SQLSTATE[42703]: Undefined column: 7 ERROR: column t.create_survey does not exist LINE 1: ..._name", "t"."parent_id", "t"."lang", "t"."email", "t"."creat... ^

Any hints how I can fix this?

Thank you & best regards
Herbie
