"Use estimated metadata" is true and i see (in wireshark!) qgis is only fetching 100 samples to get the geometry. But even that needs a very long time. I think, Postgis is doing a sequential search but i'm no shure about that. But why does Qgis check the geometry? it is allready known and should not be necessary. This part of Qgis is for me like a Black Box: select your data and wait. No loggin, no infos, nothing. Just wait. That is very frustrating in the developement-phase of a map. Killed the Qgis-Process dozend times a day, loaded my last save and started again. :( Regards walter -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Trouble-with-PostGis-plugin-tp5166669p5166851.html Sent from the Quantum GIS - Developer mailing list archive at Nabble.com. _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
