[postgis-users] shp2psql problems

There is some nasty code which is corrupting the DBF file handle after 
it is opened. Dave thinks probably an array is getting written out of 
bounds. Anyhow, it turns out there is a workaround, and that is to 
rename the file to a shorter name (??!?!). I found three-letter names 
working OK. Jeff has to spend some time communing with a debugger in 
order to track this one down.
