Notification on subversion update

Hi,   my english is very bad, i speak spanish

Is possible to get a custom notification when I do an update?

My problem is: some revisions needs to execute some scripts in the database. I want to "tag" the commit of these revision, and when someone updates to this version, see a "popup" with a notification about the need of script execution.

For example:

If the commit message is something like that:" Field F added to the table T #{Need to execute script x.sql}"

whoever get this revision, see a notification with the message "Need to execute script x.sql"



Is possible, or something like that?
Thanks
