Any thoughts on this yet? Or is this just a really stupid question? I am open to suggestions on how to make transfering data in and out of PostGIS easier.

Subject: [postgis-users] WKB to native geometry using BULK COPY
I am curious how I can use the COPY commands to insert literal geometry data. Currently this works with WKT by specifying the geometry as:
However, I would like to do the same thing using WKB. Any ideas on how that might successfully be done?
It seems I will have to get an SRID and a WKB geometry, in hex preferably, and combine the two to form a single hex literal to be inserted directly into a column of type GEOMETRY.
When I am using single INSERT statements instead of the COPY commands I use the 'geomfromwkb' function to combine the SRID and WKB hex string, so I guess what I really need to know is how this is accomplished and likely what the native underlying geometry looks like.
