Subject: [postgis-users] Merge all polygons from a dataset
I've converted a shapefile of Europe to PostGIS. I would like to merge all the countries together so that I only have one polygon left, the whole contour of Europe. I have tried ST_Union that gives me no result. I've tried several other functions to no avail. Does anybody know how I should proceed?
