Condensation is forming in visible clouds because a sudden pressure drop has cooled the air, bringing the air in that region to a temperature/pressure state where the water vapor condenses. The pressure over the wing, in particular is lower than the surrounding air and the molecules are actually further apart, not closer together. No "pushing" is going on. That's what you see the clouds form on the lee side of aircraft protrubences (like the canopy) or other areas where there is some flow separation, and not ahead of them - that's where the real compression of the air (pushing) is going on.
