# This task does a couple of things. First, it drops and re-creates
# the DB_NAME database (or schema, whatever). Then, it adds PL/pgSQL
# support to the database.
#
# At that point, we import the two PostGIS files, postgis.sql and
# spatial_ref_sys.sql. The postgis.sql file contains the geometry
# functions, while spatial_ref_sys.sql contains a table of SRIDs, and
# their associated properties. PostGIS requires both.
#
# Then, we import the Tiger data using shp2pgsql. The shapefiles
# should exist, since this task depends on the "data" task, which
# downloads said shapefiles.
#
# Finally, we create the table for the demographic data (obtained from
# the geographic header records), and populate that table with the output
# of the sf1blocks2sql script.
