Hi All,
I am new to this so forgive me if the question is stupid. I am trying to migrate my companies GIS production to PostGIS/postGres SQL. We were using ESRI File Geodatabase with SDE before this. So the problem is I want to restrict the values that can be entered in a specific column of a specific shape file but haven't been able to do it. For example if there is a shapefile called Hydro_points and it has an attribute column call Hydro_type I want only the values 1, 2 or 3 to be entered here. That table should not accept any other values and if these 3 values can be shown as a drop down box even better. We plan on using QGIS to do the production and I have gone through every inch of setting available in pgadmin III as well Please help, MaheshKrishnan
