Argh sorry, self inflicted wound (the other conflicting PR is mine 😅 ). |

Ooh, does this mean the https://github.com/erikjohnston/synapse-find-unreferenced-state-groups is getting less in the future? |

Currently purging a complex room can lead to a lot of orphaned rows left behind in the state groups tables.
It seems it is because we are loosing track of state groups sometimes.
This change uses the
room_idindexed column ofstate_groupstable to decide what to delete instead of doing an indirection throughevent_to_state_groups.Related to #3364.
