NetworkAndSiteNotificationTypesUpgradeTask fails when upgrading to 3.3 on Oracle (and probably others)

• Following error is reported in the logs at the time of upgrading to Confluence v 3.3 on Oracle 10.x:

  ERROR [main] [confluence.upgrade.upgradetask.NetworkAndSiteNotificationTypesUpgradeTask] doUpgrade Error while upgrading notifications table
  java.sql.SQLSyntaxErrorException: ORA-00904: "FALSE": invalid identifier
  

• Upgrading to Confluence v 3.3 on SQL Server reports a different error:

  ERROR [Thread-1] [confluence.upgrade.upgradetask.NetworkAndSiteNotificationTypesUpgradeTask] doUpgrade Error while upgrading notifications table
  java.sql.SQLException: Invalid column name 'false'.
  

In both the above cases, the upgrade completes successfully and there are no immediate side-effects related to the these errors.

• When creating or updating pages post upgrade, or when attaching files, the following exception is experienced:
