You could add the reproduction steps from #3442 as the test. |
In this specific case, when we create a hypertable then we add a "not-null" constraint to the "time" column if it does not exist. That is done via an internal ALTER TABLE subcommand in dimension_add_not_null_on_column function. If the currentEventTriggerState structure is enabled then it's necessary to set up the command tracking appropriately, otherwise crash ensues. This has been fixed via this now. Includes test changes.
