If you have full control of the postgis layers, you can serve them reprojected into EPSG:900913 (or EPSG:3785) and put it on top of VE/Yahoo.
You cannot (as chris points out) change the projection of VE/Yahoo (or google for that matter). They serve their baselayers in spherical mercator, and you've to adept your data to their standards if you want to use their data.
