Advanced user of PostGISCompare with other Database Spatial Tools, Postgis is very fast and free. The Postgis's community is very hardworker and solve all problems which I faced. Postgis's documentations make the learning process very easy and understandable. As a GIS Developer I use Potgis everyday of my life and I am very happy to use Postgis.
Data Visualization must improve when you want to visualize the big data postgis don't response that. That is the one and only bad thing in Postgis for me.
If you want to be a GIS Developer, You must learn the PostgreSQL and especcially Postgis.
I had big problem about the creating the Polygons via using tables row and I solved this problem via using postgis functions (st_geometrycollection, st_geomfromtext etc).
