Hello everybody, today I tried to perform a union on 59000 geometries, but the operation seems not to complete. In no way I'm an expert in PostgreSQL/PostGIS optimization, and for sure my system is not in the perfect shape to address such operations with elegance.
My questions are: * should PostGIS be able to perform this operation if properly optimized? and * could you please advise me some piece of documentation for learning about PostgreSQL / PostGIS optimization? I read somewhere that the french cartographic service has migrated to PostGIS, so I have no doubt that this have to be possible to achieve, and speaks loud about the importance of optimization issues.
