./manage.py migrate notes
Running migrations for notes:
 - Migrating forwards to 0006_auto__add_field_userprofile_hash.
 > notes:0004_auto__add_field_userprofile_hash
FATAL ERROR - The following SQL query failed: ALTER TABLE "notes_userprofile" ADD COLUMN "hash" varchar(255) NOT NULL;
The error was: column "hash" contains null values

 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running
 ! schema-altering statements in transactions, we have had 
 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   = ALTER TABLE "notes_userprofile" DROP COLUMN "hash" CASCADE; []
   = DROP TABLE "notes_userprofile_courses" CASCADE; []

 ! The South developers regret this has happened, and would
 ! like to gently persuade you to consider a slightly
 ! easier-to-deal-with DBMS (one that supports DDL transactions)
 ! NOTE: The error which caused the migration to fail is further up.
