How to import US ZCTA shapefile into PostGIS-enabled Postgresql db

	1. Download US Tigerline ZCTA shapefiles (I pulled entire US, 2013 version at time of this gist)

	2. Ensure GDAL is installed w/ postgresql flags
	// see http://gis.stackexchange.com/questions/33346/how-can-i-update-ogr2ogr-to-include-the-postgresql-driver
	brew uninstall gdal (if installed)
	brew install gdal --with-postgresql

	3. Convert and import ogr2ogr (my db name is gis_data)
	// -nlt MULTIPOLYGON needed b/c it will try to import as regular POLYGON and fail
	// NOTE: this will fail if table already exists w/same name (use --append or delete the table to start over)
