DB upgrade from 1.9.3 to 1.9.4,5,... Duplicate entry '11'

[wberry]

Hi I'm using mysql to attempt to upgrade the database from 1.9.3 to 1.9.4
from the command line I change to the DB1.5 directory and run step 1 command : mysql <database name> <db_schema_update.sql

But I keep getting the following error: ERROR 1062 (23000) at line 28: Duplicate entry '11' for key 'PRIMARY'

I'm a database novice so any help would be great.

Thanks,
Wayne.

issue is related to an already existent record on node_types.
If you remove it from table before upgrading or remove the insert from upgrading scripts, everything will work ok.
