Luckily clipping data within the postgres environment is trivial with the little help of SQL. However I wanted something a little more fancy - a way to iterate through all my spatial tables and clip out an arbitary polygon, saving the result to a shapefile. To achieve this I wrote a little bash script that does just that.
