I have never seen any deadlocks in Postgres that were caused by the driver or Postgres itself.
Deadlocks are almost always caused by sloppy programming.
My guess is that this vendor initially supported "some other" database
with less strict transaction handling or even a DBMS where the couldn't
(or didn't want to) use transactions.
