Description (last modified by )
What steps will reproduce the problem?
- the tiger geocoder relies on the 2006 and below which tiger files which
were in the proprietary Tiger format. In 2007 census switched to using ESRI shape file format and corrected a lot of data.
- Most people I know want to use the new stuff, but the structure has
changed quite a bit. E.g. the address file is now a separate table called addr and can have a 1 to many with the edges table (what used to be complete chain)
- This will all take a bit of work. Not sure if Steve Frost has started
this work yet or not.

I've already updated the geocoder itself to use the TIGER 2007/2008 shapefile data. I'm working with someone else on improving it further as well as improving the load scripts to build the whole system.
If you have git, you can pull the latest from here: http://www.snowman.net/git/tiger_geocoder
Once it's working well with the import scripts, the 2008 data, etc, I'll be committing it back to the PostGIS SVN. I'm on the hook to complete this work before PgCon 2009 (in May).
