Rép. : deadlock detected

It means that 2 sessions were waiting for each other:

E.G.:
Session 1: lock table A
=> OK
Session 2: lock table B
=> OK
Session 1: lock table B
=> WAIT until B releases the lock
Session 2: lock table A
=> WAIT until A releases the lock

Everbody is waiting, until sth/so breaks this.

AFAIK, Pg has a builtin deadlock detection, which will rollback one of the sessions and let the other work.
