To delete trac tickets without installing extra plugins, here's the SQL.
Note: make sure to create a backup of trac.db first.
$ sqlite3 trac.db
delete from ticket_change where ticket = <TicketID>;
delete from ticket_custom where ticket = <TicketID>;
delete from ticket where id = <TicketID>;Replace "TicketID" with the ID of ticket that needs to be deleted.
To purge out all tickets, use the same sql without the where clause.
