Unfortunately there is no software support TopoGeometryColumn, so i have to make a view by calling topology.Geometry(TopoGeometryColumn) to convert TopoGeometryColumn into polygon. The view creation takes a long time to complete. It spent nearly half an hour to finish that process for 22.000 records. Do you have any information on how to speed up the process?

I'm impressed it's been so quick actually :)
The whole topology support is a draft implementation,
just a kind of proof of concept.
Does the result look correct ?
People on postgis-devel would be interested in knowing about it (added in Cc).
