update batch_log set status=('in-progress'), updated_at=now() [...] returning id, batch_log.update_at ;
column batch_log.update_at does not exist LINE 14: returning id, batch_log.update_at HINT: Perhaps you meant to reference the column "batch_log.updated_at".
This does not make a whole lot of sense. It is recommending that I do what I am doing!
Also I don't see why this would fail.
Its informing you, apparently correctly, of a possible typo in your query. You wrote: returning ... "batch_log.update_at" but the spelling for that field is in past tense "batch_log.updated_at" - note the "d" on the end of the word "update".
