The triggering system of MySource Matrix uses the sq_trig_hash table to cache out various config information that speeds up the processes of looking for triggers that need executing when an action is performed. This table did not have a primary key defined. This weeks upgrades for 3.6.x and 3.7.x provide a query to add a primary key to the sq_trig_hash table.
There is no general MySource Matrix developer news this week.
Some query changes were committed this week to ensure all INSERT, UPDATE and DELETE queries are executed within transactions. This is sometimes overlooked and wasn't so much an issue with PostgreSQL as it COMMITs the transaction when the script ends regardless of if an explicit COMMIT has been executed.
New stable and release candidate versions of MySource Matrix were tagged on Monday and are available for client updates. These new versions have not been posted on the web site.
