Description

let me introduce you with my problem:
all of this began after we created some resources queues on postgresql,
well we created it, assign it to the users and all was fine...
until we run a process (a large one iterative query) and I do an Alter Role over the user and the resource queue that he was using, before that I can't login whit the user and got a message saying "deadlock detection, locking against self"
does you have any idea why this for? or if have any comprensible log in to I can search for more information?
