[postgis-users] spatial index for topology?

[William Kyngesburye]

Is there any way to spatially index topogeometry?

If I try to add either a gist or spgist index on a topogeometry column, I get an error:

ERROR:  data type topogeometry has no default operator class for access method "gist"
HINT:  You must specify an operator class for the index or define a default operator class for the data type.

pgadmin3 doesn't allow me to choose an operator class when creating the index.

I see that the raw topology data is indexed (nodes, edges and faces), but that doesn't help the topogeometry.  It looks like the whole table is being scanned when I identify a feature in QGIS.
