Comment 1 for bug 1053663

I think that for the transitional period where Trac is still running, Trac will need to be modified to send notifications to Frack.

Alternately, we could modify the postgres schema as described in http://stackoverflow.com/questions/5412474/using-pg-notify-in-postgresql-trigger-function and then use LISTEN from frack, so that we don't have to touch trac's code. But Frack still has to find out about changes that it didn't make itself.
