Thank you for the comment. I think we do. What I found odd here is the Query Plan (with analyze) clearly shows the actual execution to be very quick, that's why I don't think it's an index problem. What do you think?

Hello All.
First timer here, long time user though. Thank you in advance.
Can someone help me understand why my simple DELETE query is so slow to run?
Not familiar with citus to diagnose any citus issues. Having said that, can you confirm that all tables that have a foreign key reference to this table have an index on the field referencing?
For example, if you have a table customer, with a column 'customer_id', a table 'customer_employee' might refer to the customer table if it has 'customer_id REFERENCES customer', which would be very slow with deletes on customer. that may not be happening here with the citus stuff, hard to tell. Something to rule out though.
