IME most pedestal basins are attached to the wall by very modest
screws, and rely on the pedestal for most of the support. That's
not to say you can't firmly attach the basin to the wall.

Thick galvanised brackets screwed to the wall make a fairly neat
support, the back of the basin slots down into them. A dollop or
two of silicone sealant gives additional help.
