I am new to postgis and I would appreciate your help. I have a shape file where some polygons are duplicated (or almost the same) and I would like to remove the duplicate ones. I cannot apply the distinct on geometry because that would delete some of the duplicates I need. Here is what I need: 1. 2 polygons have same geometry but different attributes - I need both; 2. 2 polygons have same geometry but one has data attached to it, one does not. In this case I want to remove the one that has no data. 3. 2 polygons have same geometry but none have data - I want to keep one. In the same file I also have a different scenario: the areas of the "duplicated" polygons are slightly different.
I appreciate your help.

Then you can export it as script and modify it. There isn´t a lot of info about this topic. Arcgis help is not very useful ( sometimes the help examples doesn´t work). You have to be careful with python versions supported by your arcgis version ( there is info in ESRI forums about how to change your python version, and wich are suported). There is a geoprocessor model pdf, but no info about toolboxes methods... It´s a try-error process to understand each toolboxes' methods... And as you can find in ESRI forums, sometimes it doesn´t work... I´ve got some docs recopilated about this topic. If you´re interested send me a mail.
