Does the svn trunk work any better for you?

I have not used the svn trunk as yet. I will try this and keep you posted. Thanks.

I can recreate this bug locally; it's another symptom of the varlena changes in PostgreSQL 8.3, so you will not see this bug with older PostgreSQL versions. Will update this bug when the problem has been found and the issue fixed.

This should now be fixed in SVN head and will appear in PostGIS 1.3.3. Many thanks for the bug report!
