Re: BUG #19078: Segfaults in tts_minimal_store_tuple() following pg_upgrade

Hi. I was able to reproduce the crash with the simpler (non hash-agg) plan from the previous message.
Basically I launched it in multiple infinite loops that do BEGIN - UPDATE - ROLLBACK. Other clients could also modify the tables during this time.
We've seen this query crash on multiple physical hosts.

Original query:

> update Tcv_scenes cs
> set
> state_id=2,
> stitching_server_id=null,
> stitching_server_pid=null
> from
> tcv_scene_datas cd -- Partition key: RANGE (cv_scene_id)

> (cs.state_id=3 and cs.date_state_mo<now()-interval '5 minutes')
> )
> returning cs.id
