Upgrade error: org.postgresql.util.PSQLException: ERROR: column this.external_id does not exist

Question

Hello,

So I did the upgarde installation as instructed, upgrading Confluence 5.0.2 to 5.3 and got the following error message when trying to access Confluence:

org.postgresql.util.PSQLException: ERROR: column this.external_id does not exist

Any ideas how to proceed? Thanks so much!
Cheers,
Jussi

I discovered that this is not the real error, this is the web gateway crashing with a 500 error.

In order to find the real error I had to go to http://myserver:8090 to get the real error, which was very clear and consice about what I had to fix.
