@vincbeck - I have a reason to believe this has been caused by some of the 
recent changes in setup/teardown or some recent optimisations in the core of 
scheduling or some (this is a bit of a wild guess of course, but I think it 
only started to appear relatively recently (1 week or so). 
   
   I seriously doubt it has anything to do with Dask, it's more triggered by 
Dask because of it's distributed nature that can run task in much more parallel 
and disstributed fashion.
   
   It occurs exclusively on Postgres and I think I **ONLY** saw it with 
Postgres 11. And it awfully looks like a REAL problem to diagnose and solve 
before we hit 2.7.0 - if we hit it that often in tests with a single backfil, 
then in production it might happen very, very quickly.
   
   As written in https://github.com/apache/airflow/pull/32780 I will be less 
available the coming week, so maybe if someone can take a look that woudl be 
great. In the meantime merging #32780 should mitigate the failures we have in 
main and isolate that one until we fix it.
