You'll need the postgis stuff I think.
use the shp2pgsql tool, like this:
shp2pgsql -D -S geography geography > geography.sql
-D write dump format (ie COPY)
-S creates simple geom's, if you get an error, remove the -S.
USAGE: shp2pgsql [<options>] <shapefile> [<schema>.]<table>
If you wanna see the data right from the shapefiles, you can use a tool
like qgis.
.dbf is regular dbase file
.shp is a shapefile (esri shapefile)
.shx is an index
