  Don't honestly think the post anchors will hold a fence of that height once the wind starts blowing...... terrific force will be put on the bolts. As Stuart said, fixing vertically to the wall if possible, is really a much better option.

  The exception here, of course is that if the fence run is short - I'd say 18' or less and the rails each end are fixed to solid objects like existing walls you may get away with top fixing in between...
  As for me I'd not like the idea of doing this and would always build as Stuart or Gary says, posts in ground, maybe secondary fixings into or through the wall. Ihave done a few like this and they have lasted (2 for 7+years so far).

  I would go with the post up the side of the wall resin fixed in and a second post bolted to it. If you were to resin fix the post anchors to the top of the wall the base plate and the threaded rod would still be attached to the wall, the weld on the base of the anchor would quite possibly snap though after a high wind.
  
  I done my fence at home along the edge of my drive with the studding resin bonded in to the ground, partly to save time and because I didnt want to dig up parts of the drive. It was OK for a year then we had some high winds and a post anchor snapped, all of the posts are now concreted into the ground! I learnt the hard way!

  I replaced a few rotten panels on a housing estate last year. Every house had 6ft high fencing running along double skinned brick walls. Every post was sat in a custom-made fencepost socket on a saddle that straddled the wall. The saddle was bolted straight through. They didn't look great but were very secure. Like this:
