What are the advantages of PostGIS?

PostGIS provides a very robust geospatial function library of both 2D, 3D, and raster functions. It has full support for many spatial reference systems (SRS), and plugs into popular 3rd party tools to provide missing functionality, such as for visualizations or routing algorithms.

Is PostgreSQL suitable for big data?
