[postgis-devel] Postgis topology creation - O(n-squared)? - creates problems with large datasets.

Steve: "It is a little less obvious that all the work done in a function call is 
also done in the context of a transaction. So when you call a function 
like say ST_CreateTopoGeo(...) that this is implicitly run inside a 
transaction."

Steve and Sandro,

Thanks for improving my knowledge about this. 

Graeme.
