+# 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, lwpostgis.sql and
+# spatial_ref_sys.sql. These are magic as far as I'm concerned, but
+# PostGIS requires them.
+#
+# 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.
