-- Remove messages from the device_inbox table which were orphaned
|
|
-- when a device was deleted using Synapse earlier than 1.47.0.
|
|
-- This runs as background task, but may take a bit to finish.
|
|
|
|
-- Remove any existing instances of this job running. It's OK to stop and restart this job,
|
|
-- as it's just deleting entries from a table - no progress will be lost.
|
|
--
|
|
-- This is necessary due a similar migration running the job accidentally
|
|
-- being included in schema version 64 during v1.47.0rc1,rc2. If a
|
|
-- homeserver had updated from Synapse <=v1.45.0 (schema version <=64),
|
|
-- then they would have started running this background update already.
|
|
-- If that update was still running, then simply inserting it again would
|
|
-- cause an SQL failure. So we effectively do an "upsert" here instead.
