Yes on the A319 you have triple hydraulics. If you lose all three while in the air you are dead.
On the A320 series, loosing one hydraulic system has no serious effect. Loosing two starts to increase the workload a lot, for example lose the green and yellow hydraulic system, you loose the ability to operate the flaps among many other things. Dual hydraulic failures lead to a fairly complicated procedure too...in the G+Y failure ECAM actions, dual hydraulic failure QRH, Slat/Flap jam QRH, landing distance calculations and manual gear extension QRH. High PNF workload!
