Issue When Upgrading From 4.2.9 To 4.3.2

[mr1716]

I have a few custom plugins, and havent had issues when I upgraded from 4.1.11 to 4.2.9, but when I did the upgrade to 4.3.2, I got an error message on the PostgreSQL DB saying that there's a duplicate column, but I have an empty DB. The specific error is
psycopg.errors.DuplicateColimns: column of relation already exists..."

But I thought I cleaned the DB and the migration. Is there a way to force the DB to clean as this same code worked well and fine on another system I used.
