Eh. See http://trac.osgeo.org/postgis/ticket/1224 -- you're in a good
position to add more detail on what's missing now.

The thing is that PostGIS didn't use to care about edge linking at
the very beginning of topology. Now it partially does, but evidently
still doesn't for face geometry building (or I'd have expected some
kind of indirect failure from ValidateTopology).

Do you use the QGIS TopologyViewer to "visually check" ?
That one shows edge linking via labels and direction decorations :)
