Comment(by robe):

 Have logic to load blockgroups (bg), census tracts (tract) and tabulation
 blocks (tabblock) at r9168.

 I tested the differential state load on windows, but haven't retested the
 full load.

 Can you give it a try.
 After you run the upgrade script, you just need to do something like


 {{{
 SELECT loader_generate_census(ARRAY['TX'], 'sh');
 }}}

 To load for just the census data for Texas.

 As far as functions to use it, haven't thought what things would be most
 useful to output given a geometry.

 Would the full geoids be too much.  Since I deal with just state data, I
 usually use the tractce and blkgrpce (from block groups).

 I'm thinking of renaming those fields to just tract, blkgrp but I should
 probably leave well enough alone.
