Jean,

My understanding is that the GPL in this case only applies to the PostGIS
module that loads into the Postgresql server process.  It does not impact
OGR or applications using OGR since they interact through with Postgres
but are not part of the same application.

If you were still concerned about this you might want to raise the issue
on the PostGIS list, but I really don't see that the license of PostGIS
would apply as broadly as affecting your application too.  Of course, it
is exactly these sorts of complications and concerns that I try to avoid
by using the MIT/X license.

Best regards,
