Which version of PostGIS are you using ? You have to check to have at least select grants to the geometry_columns table (in postgis 1.5) or view (in postgis 2.0) in public schema. If you can't access to this table qgis spends a lot of time in order to scan all geometries of all layer.
with PostGIS < 2.0 you also have to manually register you layer into the geometry_columns table regards Luca 2014-03-28 13:38 GMT+01:00 Nico Alberti <n...@langhirano.it>: > Hi everybody.
