Craig,

In normal situations I can't see any reason the FID column should not
be the primary key.   There is currently no way to make CreateLayer()
make the OGC_FID column the primary key as part of it's operation.
I can't see any harm in adding that though.

What would I change the following to, in order to make OGC_FID
the primary key?

                 "CREATE TABLE \"%s\" ( "
                 "   OGC_FID SERIAL, "
                 "   WKB_GEOMETRY %s )",

Best regards,
