 Actually an user could access directly to the tables and a wrongly query
 could destroy the topology.
 As esample an user could think to execute this query:

 delete * from edge_data where left_face=right_face to remove dangles

 But this query could destroy the topology because don't update the node

 Instead the right query is this:

 delete ST_RemEdgeModFace(idedge) from edge_data where

 this correctly update also the node table.

 To avoid this , a good choice should be deny the access
 (write/update/delete) directly to the tables using and allow the access
 directly only to a user with a "topology_master" specific grant.
 And leave to all the user only the "read" grant to the tables.
